6a88443089 Rust: Vendor support for Rust static libraries.
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.

Since rust_ffi_static modules will link against rlibs, we allow rlib
linkage into vendor as well, but only for the variants which use the
rlib libstd.

Bug: 172525289
Test: New Soong tests pass
Test: Example vendor cc_binary links against rust_ffi_static module.

588aae727b Add rust_protobuf module.
This adds a new SourceProvider module type to handle protobuf code
generation. See the new test for an example of how to call this.

fabaff6bd7 rust: strip libraries and binaries
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

(stripped, with this change)
$ find . -name \*.dylib.so -print0 | du -c --files0-from=-
42380   total

4fef93c53f Add SourceProviders and a rust_bindgen module type
Add SourceProvider modules which provides a base interface for more
complex code generation usecases such as bindgen. Also adds the
rust_bindgen module type which calls bindgen to generate Rust FFI
bindings to C.

Bug: 159064919
Test: Local test module generates bindings.
Test: New Soong tests pass.

92f703b084 Add clippy-driver build rule
Depending on the location of the repository (e.g. external/, vendor/), a
different set of lints will be enabled. Add the clippy property to the
rust_* modules. This property can be used to overwrite the default
behaviour.

Test: m checkbuild

e4d12a0468 Add rust-project.json generator
Because we are not relying on Cargo.toml for our crate dependencies,
we need to provide a structured file to rust-analyzer which describes
the locations of the crates. Add a generator for that purpose, similarly
to cc/compdb and cc/ccdeps.
