[sanitizer] Add CMake flag to build with internal symbolizer

This intermediate result in moving internal symbolizer build
from sh script to CMake rules.

The flag is supposed to be used with:
-DLLVM_ENABLE_PROJECTS="clang;lld;compiler-rt" -DLLVM_ENABLE_RUNTIMES="libunwind;libcxx;libcxxabi" -Sllvm-project/llvm

After converting sh script into cmake, we may add support for other build modes.
