Reviewed by David Kilzer.

Adds fuzz target that are not built by default WebKit build.
Build by
  make release SCHEME="Fuzzers (ANGLE)" ASAN=YES LIBFUZZER=YES

ANGLEShaderTranslator
 - fuzz target
 - links statically to libtranslator (see below)

Adds the existing metal_translator_fuzzer to this "Fuzzers (ANGLE)"
aggregate target, too.

Adds fuzzing tools that are not built by default WebKit build.
Build by
  make release SCHEME="Tools (ANGLE)" ASAN=NO LIBFUZZER=NO

ANGLEShaderTranslatorCoverage
  - XCTest project to run the corpus with the compile flags of
    ANGLEShaderTranslator
  - Can be used to verify the coverage of the corpus

ANGLEShaderTranslatorStats
  - Used to analyze RSS increases when corpus is run
  - Run the corpus with the compile flags of
    ANGLEShaderTranslator

Adds a static library that is not built by default WebKitBuild

libtranslator
  - Compiles translator again, to be linked statically to the fuzzer
  - In later commits, may be linked to libANGLE-shared. Not done
    in this commit to avoid breakage.
