tldr: remove protobuf2 from Android Rust and upgrade everything to pb3.
These commits update:
- The grpcio rust crate to use protobuf 3
- The build system to always use the new libprotobuf (pb3) instead of the _deprecated variant (for pb2); they also force-enable libprotobuf everywhere, ignoring the use_protobuf3 flag, removes the tests related to pb2
- The following modules, which required syntax changes:
-- packages/modules/Bluetooth
-- device/google/cuttlefish
-- vendor/auto
Bug: 308790516
Test: m rust
Ignore-AOSP-First: must be done in main to upgrade cuttlefish+vendor with the rest all at once

rust_protobuf were unable to import protos from other rust_protobuf
modules. This CL adds support for that. rust_protobuf modules which are
listed in rustlibs will have their modules imported into the generated
protobuf stub. Additionally, rust_protobuf modules which define
"exported_include_dirs" will export those include paths to dependent
rust_protobuf modules.

Users of the rust_protobuf module can use the 'use_protobuf3'
option to select version 3 of the protobuf crate instead of the
current default of version 2. This unblocks teams that would like
to use protobuf 3 immediately and provides a mechanism for us to
incrementally migrate users of protobuf 2 to protobuf 3.
Test: Adds tests that are executed during every build.

Replaces the rust specific rustTestCtx mechanism with the general test
fixtures mechanism as converting it to use preparers was not possible.
Also, removes usages of the buildDir variable and removes it as it is
no longer needed.

To allow grpc protobufs to include non-grpc protos in a singular
library, we need to allow them to be defined as part of the same module.
This CL merges the two previously distinct module types into
rust_protobuf, and adds a new property for declaring which protos
contain grpc definitions.
Bug: 172952239
Test: rust_grpcio modules converted to rust_protobuf modules and build.
Test: Example rust_protobuf module with both proto types builds.

This further emulates the rust-protobuf gen_mod_rs flag by providing
support for generating a single module containing multiple protobuf
definitions.
Bug: 171361369
Test: New Soong tests.
Test: Example module containing multiple protos works.

The usage of the well known type Empty requires a hack in the module
above the grpc implementation, this is now the generated stem_mod.rs
This also adds additional implicit dependencies that are required by
the grpc protobuf generated code. This includes the addition of a
'header_libs' property for library dependencies which export include
paths required by protos.
We also now include both the protos and the grpcio in the library
variant via the mod_stem.rs.

Test: Example rust_grpcio module build command includes dependencies,
include paths.

Adds a new SourceProvider type to generate grpcio code from protos.
Since it's so similar to protobuf, it's basically just a different type
of rust_protobuf.
Bug: 171504899
Test: Example module compiles.

This reverts commit 323dc60712.
Reason for revert: Possible cause of test instability
Bug: 170513220
Test: soong tests
Change-Id: Iee168e9fbb4210569e6cffcc23e60d111403abb8
Putting t.Parallel() in each test makes them run in parallel.
Additional t.Parallel() could be added to each subtest, although
that requires making a local copy of the loop variable for
table driven tests.
Test: m checkbuild

Until now, source provider modules duplicated the rule to generate the
source for each variant. Add a inter-variant dependency between the
source and the other variants (e.g. rlib, dylib) to avoid this
duplication. Add documentation on this behaviour.

This adds a new SourceProvider module type to handle protobuf code
generation. See the new test for an example of how to call this.
Bug: 143953733
Test: New soong tests pass.
Test: Replacing genrules in crosvm with rust_protobuf modules.
