CC libraries generate TOC files which contain the list of exported
symbols. By depending on the TOC file instead of the .so, changes to
shared library dependencies will not result in rebuilding Rust
dependencies as long as the exported symbols remain unchanged. This
should improve incremental build times during development.
This also includes a minor fix where exported linkObjects should be
deduplicated to avoid the same object being included many times.

Rewriting LLNDK dependencies with .llndk suffix requries referencing
a global data structure to determine if a given library is an LLNDK
library and therefore needs the .llndk suffix. References to
global data structures from mutators must be removed to support
incremental Soong analysis. Instead, move the LLNDK stubs rules
into the vendor variant of the implementing cc_library so that
the original name can be used.
As an incremental step, the llndk_library modules are left in
place, and the properties are copied into the cc_library via
the dependency specified by the llndk_stub property. A followup
will move the LLNDK properties directly into the cc_library and
delete the llndk_library modules.
The global list of LLNDK libraries is kept for now as it is used
to generate the vndk.libraries.txt file.

We don't have Rust VNDK support yet, but static linkage can be
supported in the interim. This adds support for making rust_ffi_static
libraries available to CC vendor modules.

Previously, the dep tag used by PackagingBase was fixed, which prevented
some of its clients (e.g. cvd-host-package) from opting in to
android.InstallAlwaysNeededDependencyTag. Now, PackagingBase.AddDeps
accepts the dependency tag to use.
Also, dependencies toward rust dylib, rlib, and proc_macro are
configured to return true on InstallDepNeeded. This is required to
install shared_lib dependencies of the rust modules when they are
depended on by a rust binary.

Export information about static libraries, shared libraries and
exported flags through Providers instead of accessing the module
directly. Much more is left to be converted, but this significantly
simplifies the dependencies on libraries with stubs by making it easy
for a module to masquerade as another by simply exporting the
providers from the other module. Instead of depending on all the
versions of a library and then picking which one to use later, it
can depend only on the implementation variant and then select the
right SharedLibraryInfo from the variant.

The current state of linkage is that device targets always link
libstd dynamically except for rust_ffi_static which requires a static
libstd linkage. However this prevents producing rust_ffi_static
modules which depend on other Rust libraries as those dependencies
will link libstd dynamically and cause a collision. We also want our
rust_test modules to statically link in libstd as well.
This adds a linkage mutator for rlibs that creates a variant for each
libstd linkage. Dependent modules can then select the variant that
matches their linkage of libstd.
Also fixes an issue where installation paths were being generated for
rlibs and static libs even though they weren't being installed. This broke
when adding the linkage mutator as Make would complain about multiple
targets producing the same output.

A per-context variable is used to store the list of modules that
contain stubs and their available versions. Stores the list of the
stubs versions on the implementation module, and then use the new
return values from AddVariationDependencies to expand dependencies
on implementation libraries to also depend on the stubs libraries.
Adds a new mutator pass to propagate list of stub versions to llndk
libraries.
Also creates an alias version variation called "latest" to allow
depending on the latest version without having to know what it is.

With If4300583edfb6d75bd4d984b38f73b6a406b4447, linux_bionic supports
arm64 and rust toolchain was configured to support the new target.
However, rust module types still have been disabled for linux_bionic
targets which forces many rust modules to be annotated with
target.linux_bionic_arm64.enabled: true, which will be very cumbersome.

Reuses the cc.Stripper logic. Abstracts Stripper to avoid the spreading
of references to the cc package.
rustc requires unstripped libraries (precisely, with the `.rustc`
section) when building dependent targets. Contrary to cc, the output of
a compiler module will remain unstripped and only an extra build rule
will be added. This rule will be referenced at install time (in
baseCompiler.install or androidmk).
This change drastically reduces the size of the installed libraries:
(unstripped, from out/target/product/crosshatch/system)
$ find . -name \*.dylib.so -print0 | du -c --files0-from=-
149996 total
