To support module specific lexer flags, this follows the same strategy
as the yacc flags:
- add LexProperties to the BaseCompilerProperties
- propagate those flags to the generator generation (i.e. genLex)
- add a placeholder for custom flags
- replace the placeholder with the concatenated flags
This might not support escaping very well, but I figured that this is a
very edge case. Support for escaping etc. could be added later on.

When a cc module sets UseApexNameMacro(mutated property), it is built
with __ANDROID_APEX_NAME__ for its apex variants.
For now the new prop is used by aidl_interface-generated modules only.
Note that we already have __ANDROID_APEX_<NAME>__ macro. The new macro
can be used when we need to pass the name as data while the old one is
useful when we want conditional compilation.

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.

We don't need the prebuilt versions. The NDK CRT objects are (now)
built from the platform sources and the only difference is that the
NDK CRT objects also include an ELF note that identifies the NDK
version, which isn't helpful for anything built by the platform.
Add a `crt` property to cc_object that allows CRT objects to identify
themselves. CRT objects, unlike other modules, will have a variant
built per-API level they support, rather than just an SDK variant and
a platform variant. This is needed because new CRT objects will rely
on APIs not available in old libcs and old CRT objects will not
support all the features of a modern one.

Native compiler flags are currently applied in approximately:
global cflags
local cflags
local include dirs
global include dirs
global conlyflags
local conlyflags
global cppflags
local cppflags
This means that a flag that is enabled in the global cppflags
cannot be disabled in the local cflags, and an Android.bp author
must know to disable it in the local cppflags. A better order
would be:
global cflags
global conlyflags
global cppflags
local cflags
local conlyflags
local cppflags
local include dirs
global include dirs
We are mixing both the global and local cflags into a single
variable, and similar for conlyflags and cppflags, which
prevents reordering them. This CL prepares to reorder them
by splitting the global and local cflags into separate variables.

__ANDROID_APEX__ was defined with the name of apex module.
-D__ANDROID_APEX__=com.android.foo
But in this way, conditional compilation is not easy since comparing
macro's string value is not supported in C/C++.
(There's no usages of this value in source tree.)
In most cases, modules can check if __ANDROID_APEX__ is defined to see
if they are compiled for apex.
For modules which should behave differently according to which apex they
are included, they can check __ANDROID_APEX_<NAME>__.

With __ANDROID_APEX_<NAME>__ definition, native modules may have
different behavior when it is built for a specific apex module.
Previously, the name is passed as value of definition __ANDROID_APEX__
like -D__ANDROID_APEX__=com.android.foo. But it is difficult to do
conditional compilation with it.
Now, since the name is incorporated into definition itself, it gets
easier to set #ifdef condition.

The NDK is built like this. Having it for app builds within the Android
build system allows us to distinguish platform code from app code.
This is specifically to distinguish AIDL interfaces using libbinder_ndk.
'myBinder-ndk_platform' libs will use additional functionality that
'myBinder-ndk' libs won't use (in the future, these may be separate
variants with the same name, see b/121157555).

A module can be built multiple times when it is referenced from one
or more APEXes. Sometimes, it is required for the module to behave
differently depending on the context; e.g., do A when built form
APEX M, do B when built for APEX N, and do C when built for platform.
The idea is to have a macro __ANDROID_APEX__ which is set to the
name of the apex that the module is built for. It is undefined when
the module is built for platform.

Not all projects can be built when their base directory (the
directory containing the Android.bp file) is automatically included.
For example, external/jsoncpp has a file named version, which will
