This commit adds the libbpf_prog soong module which is heavily based on
the bpf soong module. Due to issues encountered and concerns around
compatibility and testability of mainlined bpf modules, support for
libbpf is added as a separate module.
Specifically, when changing the bpf module from
InitAndroidArchModule(... android.MultilibCommon) to MultilibFirst, the
soong apex bpfs functionality breaks. We have not identified a good
mechanism to fix this, and as we would then be creating architecture
specific bpf program binarys, additional testing and infrastructure
would be required.
It should be noted that libbpf_prog should not be used for features
which target 32bit kernel architectures at this point, as we do not
have a mechanism to identify the kernel arch at build time. I.E. 32bit
userspace could be on either 32bit or 64bit kernel arch, and we require
arch specific includes (vmlinux.h). Therefore, we default to 32bit
userspace on 64bit kernel to match the precedence set with the legacy
bpf programs.
Example use:
libbpf_prog {
name: "xyz.o",
srcs: ["xyz.c"],
arch: {
arm: {
local_include_dirs: ["vmlinux/arm64"],
},
arm64: {
local_include_dirs: ["vmlinux/arm64"],
},
x86: {
local_include_dirs: ["vmlinux/x86_64"],
},
x86_64: {
local_include_dirs: ["vmlinux/x86_64"],
},
},
}

The NDK should stand alone, and the libbinder_ndk case
is created because libbinder_ndk in the NDK used to
contain extra C++ headers, but these were moved into
the SDK to be next to AIDL. Since many modules depend
on these headers, exports are only allowed for this case.

The `m Run*RoboTests` test runner is no longer supported, remove the
code to generate the Make rules for it.
Also reduce the number of combining steps by passing the extra jars
that need to be combined into the compile step.

collectTransitiveHeaderJarsForR8 visits direct dependencies and collects
all transitive libs and static_libs header jars. The semantics of the
collected jars are odd (it collects combined jars that contain the static
libs, but also the static libs, and it collects transitive libs dependencies
of static_libs), so these are only used to expand the --library arguments
to R8. Rename the method and all the fields it uses with a "ForR8"
suffix to avoid confusion when more transitive header jar collection is
added to support transitive classpaths.

Pass the name of Soong's checkbuild target for each module to
Make so that it can depend on it from the main checkbuild rule.
This will give better control over which files get built, allowing
checkbuild to skip the jar combining step when transitive classpath
jars are enabled. The per-module checkbuild targets are passed to
make instead of added directly as a dependency of checkbuild in order
to maintain the existing behavior of only building modules exposed
to make in checkbuild.
Also tweak the existing calls to CheckbuildFile and add
InstallFileWithoutCheckbuild to match the files that are
in the Make-based checkbuild.

Previously before aosp/3249712, ndk_library was assumed to depend only
on ndk_headers, which do not have any variants.
As ndk_library can now depend on cc_library_headers which has many
variants for arch, sdk, and more, the previous assumption no longer
holds.
Therefore, when ndk_library makes a dependency to its
export_lib_headers, it now uses either AddFarVariationDependency with
(for ndk_headers) or AddVariationDependency (for others) depending on
which module type it depends on.
