Previously, the deapexer module had to duplicate the java library
specific logic for constructing the path to the library's dex file in
the .apex file. That is not something that the deapexer needs to be
aware of, all it needs is a list of files that should be exported.
This change moves that logic into the prebuilt_apex/apex_set modules
and generalizes the deapexer module so that it can export any files
that are requested.
The deapexer module does still need to know which java modules need
access to exported files so it can add dependencies from them onto
itself. However, it does not need to know what the type of the module
is.

This is needed to allow a prebuilt_bootclasspath_fragment to be used
interchangeably with a bootclasspath_fragment in the
platform_bootclasspath module.
The platform_bootclasspath module depends on APEX specific variants of
bootclasspath_fragment modules. That works because the
bootclasspath_fragment modules are part of an apex and so have an APEX
specific variant which the platform_bootclasspath can specify.
Using a prebuilt_bootclasspath_fragment in place of a
bootclasspath_fragment requires that the prebuilt also has an APEX
specific variant.
Specifying exported_bootclasspath_fragments on a prebuilt_apex/apex_set
will cause it to create an APEX variant for the named module whcih will
allow it to be selected by the platform_bootclasspath module.

This dedups the apex selection (which was previously being done by both
the apex.Prebuilt module type and the Deapexer module type) by
separating it out into its own module.
The apex.Prebuilt module retrieves the selected apex from its
selected_apex property which is simply initialized with
":<selector-module-name>".
The Deapexer module retrieves the selected apex it should use from its
src property which is initialized in the same way. That makes it easy
for the Deapexer module to be reused by the apex_set in a similar way.

Previously, the private deapexer module type was treated as a prebuilt
as that was the quickest way to implement it. However, there is no
reason why it should be as there is no corresponding source module type
which it might replace.
This change removes the prebuilt support to simplify the module type in
preparation for future work. As part of that it extracts the logic for
retrieving a single path from a PrebuiltSrcsSupplier to ensure
consistent behavior.

Originally, when the prebuilt_apex was first created, it selected the
source to use in its DepsMutator. It did that because that was a
convenient place for it to perform that work which had to be:
* After the arch mutator had run so MultiTargets() was available.
* Before the prebuilt_select mutator runs as that relied on the Source
property to have been set.
Change 064b70c9 then duplicated the call from the DepsMutator of the
deapexer module type that was added as part of the work to make dex
files available for hiddenapi processing.
Change 356f7d45 moved it out of the the DepsMutator methods into its
their own mutators, presumably because it interfered with the
Soong -> Bazel conversion work.
This change improves the existing PrebuiltSrcsSupplier mechanism to
support reporting errors so that the logic for selecting the source can
be done on demand rather than in separate mutators.
The main complication was that PrebuiltSrcsSupplier is called with a
BaseModuleContext for both source and prebuilt modules so it cannot use
any methods on it that are related to the current module. That
necessitated adding MultiTargets() to android.Module.

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.
