Thiébaud Weksteen 31f1bb80ef rust: add ccToolchain to Module
The cc toolchain information is required when using cc.Stripper.
Move to a Module method to avoid importing the cc package everywhere.

Test: m nothing

Thiébaud Weksteen 9e8451e524 rust: modify linting properties
Move the linting properties to an enum with 4 possible options:
"default", "android", "vendor" or "none". The previous logic for
default, based on the module's location, is kept. It is now possible to
force the upgrade to a certain lint level for some modules (e.g.
external/[...]/android). Update the unit tests and documentation.

Andrei Homescu c7767922e0 Export Rust SourceProvider types and methods
The AIDL compiler now uses SourceProvider to compiler the generated Rust
code from system/tools/aidl/build/aidl_interface.go using its own
SourceProvider object, which needs access to baseSourceProvider and all
methods of SourceProvider.

Test: mmma system/tools/aidl with 1357705 applied

Ivan Lozano ff3a5b31c0 Make source_stem required for Rust SourceProviders
This removes ambiguity for developers with the 'stem' property.

Bug: 159064919
Test: New Soong test; error is produced if this property is undefined.

Ivan Lozano 26ecd6c597 [rust] Add SourceProviders as crates support.
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.

Ivan Lozano 45901edb9a Ensure hermetic device rust_bindgen.
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.

Ivan Lozano 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.
