When a library is included in two APEXes whose platform_apis settings
are different, two apex variants of the library is created: apex1000 and
apex1000_private.
This change was introduced with ag/15061306, especially by the commit
[1].
However, that part should be reverted because it actually creates
unnecessary variants. It's unnecessary because the two variants of the
library are compiled (excluding the linking) exactly the same. If a
private symbol of its dependency was actually used when compiling the
apex1000_private variant, then the other apex1000 variant wouldn't have
been built because that private symbol must have caused a linkage error.

The property is used to allow non-updatable APEXes to use platform APIs
(e.g. symbols marked as "# platform-only").

(cherry picked from commit fb63625a7f)
Consider this case:
apex {
name: "com.android.foo",
native_libs: ["foo"],
}
override_apex {
name: "com.mycompany.android.foo",
base: "com.android.foo",
}
cc_library {
name: "foo",
}
There are two APEXes defined: "com.android.foo" and
"com.mycompany.android.foo" which is a copy of "com.android.foo" with
some properties overridden (e.g. signing keys).
The module "foo" is mutated into two variants by the apex mutator: the
platform variant and the apex variant. The former has the variation name
"" and the later has "apex<min_api_ver>" which usually is "apex10000".
Internally, the apex variant has an alias "com.android.foo".
ApexInfo.InApexVariants() returns only "com.android.foo" when called for
the module "foo".
We can see that the information that "foo" is also part of
"com.mycompany.android.foo" is completely lost. This is causing problem
when we compare the apex membership by their "soong module name", not
the "apex name". In the example above, the two modules have different
soone module names, but have the same apex name: "com.android.foo".
To fix that, this CL introduces a new field `InApexes` to the `ApexInfo`
struct. It has the actual name of the APEXes that the module is part of.
With the example above, `InApexes` is ["com.android.foo",
"com.mycompany.android.foo"].

ApexInfo is not part of the properties struct. It can handle structs
having private fields.

This test does not process any bp files it just needs a directory to
pass to TestConfig so it can use that to fake a PathContext. So, this
just replaces buildDir with a call to T.TempDir().

Dexpreopt and boot jars package check all require access to dex
implementation jars created for java_library and java_sdk_library. They
were available when building from source but not when building from
prebuilts, even though they are embedded within the .apex files that
are referenced from prebuilt_apex.
This changes adds support to prebuilt_apex to export the dex
implementation jars and updates java_import to use those exported dex
implementation jars.
In a source build dexpreopt/boot jars package check access the apex (or
platform) specific variant of a java_library, e.g. core-oj, from which
it retrieves the dex implementation jar path.
After this change in a prebuilt build dexpreopt/boot jars package check
behave in the same way except in this case they retrieve the dex
implementation jar path from the apex (or platform) specific variant of
the java_import, e.g. core-oj.
The work to export files from a `.apex` file for use by other modules
is performed by a new `deapexer` module type. It is not used directly
in an `Android.bp` file but instead is created implicitly by
`prebuilt_apex`,
In order to do that this contains the following changes:
* Adds a new `dexapexer` module type to handle the exporting of files
from the `.apex` file.
* Adds an exported_java_libs property to prebuilt_apex to specify the
set of libraries whose dex implementation jars need exporting.
* Creates apex specific variants of the libraries listed in the
exported_java_libs property.
* Adds the set of exported files to the ApexInfo to make them available
to the apex specific variants.
* Prevents the prebuilt_apex variants from being merged together as
they will not be compatible.
* Modifies java_import to use the exported file for variants of a
prebuilt_apex.
* Adds a ninja rule to unpack (using deapexer) the contents of the
prebuilt_apex's apex file, verify that the required files are present
and make them available as outputs for other rules to use.
* Some minor refactorings to support these changes.
* Adds tests to cover prebuilt only, prebuilt with source preferred,
and prebuilt preferred with source.

Putting t.Parallel() in each test makes them run in parallel.
Additional t.Parallel() could be added to each subtest, although
that requires making a local copy of the loop variable for
table driven tests.

A global variant was used to store the global mapping between
modules and APEXes. Replace it with storing pointers to APEX
contents inside each module so that they can query the contents
of any APEXes they belong to.

apex_test.go wasn't listed in the Android.bp file, which allowed
it to bitrot. Make the API level methods take a PathContext
so that they can be called from a test using configErrorWrapper.
Also fix an int that was converted to a string.

APEX variants that share the same SDK version and updatability
almost always use identical command line arguments to build but
with different intermediates directories. This causes unnecessary
build time and disk space for duplicated work.
Deduplicate APEX variants that would build identically. Create
aliases from the per-APEX variations to the new shared variations
so that the APEX modules can continue to depend on them via the
APEX name as the variation.
This has one significant change in behavior. Before this change,
if an APEX had two libraries in its direct dependencies and one
of those libraries depended on the other, and the second library
had stubs, then the first library would depend on the implementation
of the second library and not the stubs. After this change, if
the first library is also present in a second APEX but the second
library is not, then the common variant shared between the two
APEXes would use the stubs, not the implementation.
In a correctly configured set of build rules this change will
be irrelevant, because if the compilation worked for the second
APEX using stubs then it will work for the common variant using
stubs. However, if an incorrect change to the build rules is
made this could lead to confusing errors, as a previously-working
common variant could suddenly stop building when a module is added
to a new APEX without its dependencies that require implementation
APIs to compile.
This change reduces the number of modules in an AOSP arm64-userdebug
build by 3% (52242 to 50586), reduces the number of variants of the
libcutils module from 74 to 53, and reduces the number of variants
of the massive libart[d] modules from 44 to 32.
This relands I0529837476a253c32b3dfb98dcccf107427c742c with a fix
to always mark permissions XML files of java_sdk_library modules as
unique per apex since they contain the APEX filename, and a fix
to UpdateUniqueApexVariationsForDeps to check ApexInfo.InApexes
instead of DepIsInSameApex to check if two modules are in the same
apex to account for a module that depends on another in a way that
doesn't normally include the dependency in the APEX (e.g. a libs
property), but the dependency is directly included in the APEX.
