  Make ANGLE program version only dependent on data that matters
  
  This change introduces a new variable ANGLE_PROGRAM_VERSION
  to track the version of ANGLE source files that affect shader
  program serialization/deserialization. This change include more
  source files than necessary, to serve the purpose of a conservative
  jumping off point. We will narrow down the list of files for
  ANGLE_PROGRAM_VERSION hash generation in the future.
  
  Add a new script program_serialize_data_version.py that will
  be triggered during the build when the related source files changed.
  The script will generate a hash and the hash size from the related
  source files. In program serialization/deserialization and cache
  key generation, we will use this hash value instead of the entire
  ANGLE git hash. When the hash value changed, we know that the
  related source files changed, and we should invalidate the program
  cache and re-generate the blob cache / program binary.
