In some cases customized logic is required to generate the expected
bindgen bindings. This adds support for rust_bindgen modules to define a
HostTool module to use instead of bindgen.
Bug: 161816141
Test: New Soong tests pass.
Test: Local test case shows custom_binary module being used for bindgen
generation.

bindgen generated code may not pass clippy checks, so preemptively
disable clippy for these.
Bug: 162828070
Test: clippy is not called when compiling rust_bindgen library variants.

Bindgen generated bindings will not pass lints, so we need to disable
them when building bindings crates.
Test: m libbinder_ndk_bindgen

This allows SourceProvider modules to create rust_library variants so
that generated source can be referenced as an external crate rather than
via an include macro. This is done by including rust_bindgen modules
like any other library, as a dependency in either rlibs, dylibs, or
rustlibs.
This renames the stem and flags properties for rust_bindgen modules to
source_stem and bindgen_flags, respectively. This deconflicts with the
usage in baseCompiler.
This also removes 'subName' from the Module struct and moves it over to
SourceProvider, which was the only user. This allows us to set it in
baseSourceProvider's AndroidMk; setting it in Module's AndroidMk was
causing problems finding NOTICE files for bindgen library variants.
Bug: 159064919
Test: New Soong tests pass.
Test: Local test rust_binary can use rust_bindgen module as a crate.

rust_bindgen was not hermetic previously as it would pull in host
headers for device targets. This fixes that by using the same flags we
use when compiling with Clang. This also makes sure our rust_bindgen
headers are built as similar as possible to their respective
cc_libraries.
This also pulls in the bionic dependencies as well, which provide the
headers required for device targets.
Bug: 162007475
Test: device rust_bindgen deps file does not reference host headers.

This makes debugging easier when the bindings contain errors.
Bug: 161730753
Test: Generated bindings are formatted.

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.
