Adds the `make fuzz` build rule. This offers a few features on top of
`make haiku`:
1. Identifies all fuzz targets through the build system, rather than
having to maintain a golden file.
2. Packages now exist in out/soong/ and are packaged on a per-architecture
basis. Packages also now contain fuzzer seed corpus && dictionary.
3. This gives us further extension options:
- Packaging shared libraries for shared library fuzzing.
- Presubmit tests for fuzzing. Each fuzz target could be made into a
regression test by adding the crash testcase to the corpus. We can
also ensure that example_fuzzer finds a bug with an ASan report as a
presubmit smoke test.
Bug: 141026328
Test: m fuzz && unzip -l out/soong/fuzz-$ARCH.zip

Adds the corpus and dictionary properties to the cc_fuzz target.
Propagates these entries to the makefile backend via LOCAL_FUZZ_DATA, in
a similar manner to LOCAL_TEST_DATA.
Bug: 141026328
Test: m example_fuzzer, fuzz target should have adjacent corpus/dict
files.

Adds the host fuzzing support back for 32-bit x86 targets, now that the
toolchain has been updated to export this library.
Bug: 133261679
Test: `m example_fuzzer` on a 32-bit target/cross

Statically links libcxx in order to not require shared library
deployment during packing of fuzz targets.
Test: m example_fuzzer && ldd $ANDROID_HOST_OUT/fuzz/example_fuzzer.
Note that the ldd results don't include libc++.so.

fuzzers require linking to libclang_rt which does not support
linux_bionic. Therefore always disable this target.
Test: ./art/tools/build_linux_bionic_tests.sh

The fuzzer runtime is not present for darwin host modules, disable
cc_fuzz modules when targeting darwin.
Test: m on darwin

Adds the cc_fuzz target via a cc_fuzz module. Also implements the
libclang runtime interface for the x86 toolchain to allow host-built
fuzzers.
Bug: 133261679
Bug: 137398545
Test: Build a fuzzer (with all topic patches), notice that you now
have a host-built fuzzer :)
