Ivan Lozano 6cd99e6ab4 Add Rust fuzzing support. 
Add a rust_fuzz module which builds a libfuzzer binary that enabes
asan+sancov. This relies on the libfuzzer-sys crate.

Bug: 147140513
Test: Local rust_fuzz example builds, fuzzes with asan+sancov.

Ivan Lozano 6d45a9863a rust: Pass lld flags from cc to rust linker args. 
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.

Bug: 167690054
Test: cd external/rust; mma
Test: strace -f -e %file <host libstd.dylib.so build command> pulls
      from correct sysroots.

Jeff Vander Stoep 6e97a7b4a1 rust: Use host linker when building for Mac host. 
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.

Bug: 155302034
Test: On both Linux and Mac hosts:
    cd external/rust; mma

Ivan Lozano ffee334706 Add Rust support to Soong. 
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.

Bug: 136189233
Test: Test module builds.
Test: crosvm builds.
