By default, rust uses the `legacy` mangling format. Using llvm coverage
switches it to using the new `v0` format. Rather than pushing the llvm
coverage back to `legacy` format, move Android forwards to `v0`. This
also has the added benefit that Rust symbols can be detected in the
codebase by looking for a leading "_R", aiding in demangler selection.
Test: builds, resulting object files have leading _R rather than _Z
Test: atest keystore2_test

This allows tombstones to be symbolized and is consistent with C/C++
where we pass -g.

Rust is not passing the sysroot flag to Clang when invoking it as the
linker. This means files from the host may leak in, and host targets
may fail if sysroot files are not available from the host.
This patch prepends the lld flags from cc into rust linkargs. This
pulls in the sysroots flag, and also ensures that we remain in sync
with linkage flags used in cc.
The '-Wl,--no-undefined-version' from cc is overridden to avoid
missing version assignment errors for rust's generated alloc
functions.

Test: strace -f -e %file <host libstd.dylib.so build command> pulls
from correct sysroots.

This behavior is non-hermetic, but matches the behavior of the C++
support. On Linux, using lld works, but on OSX, this fails because lld
does not support Apple's new .tbd files.

Add documentation on how lints are defined and used in Android. Merge
the deny_warnings attribute with a new attribute (no_lint) which can be
used to disable the default linting parameters.
Explicitly allow all lints for external/ and prebuilts/, which remove
any warning when building sysroot for the devices.

This is no longer shipped by rustc, and wasn't really intended to be

* Edition and Deny_warnings should not be set when
constructing a BaseCompilerProperties, or the
initialized values will reject values inherited from rust_defaults.
* Use getEdition and getDenyWarnings to retrieve those properties
with defaults from config.

We need to pass --remap-path-prefix to Rust builds to ensure that they
are reproducible across different paths. This adds that for both host
and device builds.
Test: Verify host and device builds are reproducible with different
directories.

Adds support to Soong for building rust modules. This currently only
supports x86_64 device and x86 linux host targets. The functionality
is sufficient to build crosvm.
