This CL makes multiples changes in preparation for platform-wide CFI.
(a) Adds a second -version-script=... to the command line
when building components that use a version script. This ensures that
__cfi_check is also exported, and allows CFI to be enabled for these
components.
(b) Adds both topdown and bottom up mutators for CFI to help propagate
dependencies correctly for components that may need CFI disabled.
(c) Fixes an issue with the mutators to correctly apply settings to
both generated variants
(d) Fixes issues when components have more than a single visibility
flag.

Adding `static_ndk_lib: true` to a module installs the static library
to the NDK sysroot.

So that the contents gets replaced when prepended/appended instead of
merged.
Test: Set instruction_set in a cc_defaults, and in a module.

Added export_llndk_headers properties to llndk_library module. And a new
module type llndk_headers is added. This is to enable an LLNDK library
to reexport other LLNDK headers.
Bug: 65395259
Test: do the following
// frameworks/native/libs/arect/Android.bp
llndk_headers {
name: "libarect_vendor_headers",
export_include_dirs: ["include"],
}
// frameworks/native/libs/nativewindow/Android.bp
llndk_library {
name: "libnativewindow",
....
export_llndk_headers: ["libarect_vendor_headers"],
}
check that
-Iframeworks/native/libs/arect/include is in LOCAL_EXPORT_CFLAGS of
libnativewindow.vendor in out/soong/Android-<product>.mk

Also adds checks that the dependencies are android.Modules and
are not disabled.

Move firstUniqueElements to android.FirstUniqueStrings,
lastUniqueElements to android.LastUniqueStrings, and lastUniquePaths
to android.LastUniquePaths.

Now that android.ModuleContext does not include blueprint.ModuleContext
we can rename android.ModuleContext.ModuleBuild to
android.ModuleContext.Build without colliding with
blueprint.ModuleContext.Build. Leave ModuleBuild as a wrapper around
Build for now to avoid having to update all the users outside
build/soong simultaneously.
Test: m checkbuild

target.vendor.exclude_static_libs: this is the static counterpart of
target.vendor.exclude_shared_libs. This removes the libs from the static
dependency when build the vendor variant.
target.vendor.version_script: vendor-specific version script.
Right now, these are required to merge libseliux_vendor into libselinux
and make it vendor_avaialble:true. libselinux is using libpackageparser
which is a platform-only library. The vendor variant of libselinux can't
depend on the library.
Bug: 66914194
Test: lunch aosp_arm64_ab-userdebug; m libselinux.vendor

This uses knowledge of transitive dependencies to reorder
linker command line arguments such that if module A depends
on module B, then module A is automatically listed before
module B in the linker command line.
This should mostly remove the need for Android.bp files to
list all of their static dependencies in link order
Bug: 66260943
Test: reorder the entries of static_libs in an Android.bp and see that linking still succeeds

Leave '__unix' and '__unix__' defined on mips/mips64, like arm.
This is needed to avoid a warning in external/libcxx project.

This property defaults to 'true' and setting it to false skips profile
use. This escape hatch lets us disable PGO for a module without
completely removing the 'pgo' property. Additionally, this also helps
selectively disabling PGO for some architectures, if desired.
Test: Test that -fprofile-use is not added for a test module if
'enable_profile_use: false' is set.

linkageMutator removes srcs property of the shared variant of a lib in
order to reuse *.o files compiled for the static variant also to the
shared variant.
However, this causes problem when vendor-specific srcs are specified in
target: {vendor: {srcs: ["..."]}}. For example, let's assume
cc_library {
name: "libfoo",
srcs: ["foo.c"],
target: {
vendor: {
srcs: ["bar.c"],
},
},
}
Then,
static_vendor: inputs = foo.o, bar.o
shared_vendor: inputs = foo.o (from static_vendor), bar.o (from
static_vendor), bar.o
So, bar.o is included twice and this causes multiple symbol definition
error.
In order to handle the problem, vendor mutator is applied before the
linkage mutator and the vendor-specific srcs are squashed in the vendor
mutator.
