[Code Coverage] Implement Clang code coverage compiler wrapper
This CL implements the Clang code coverage compiler wrapper, which can
be used to instrument a subset of source files, and the main use case
is to enable generating code coverage reports at per-cl level during
try jobs.
This CL only focuses on the wrapper itself, how to hook this wrapper
into the build system will be addressed in a separate CL.
