  Reland "Make ANGLE program version only dependent on data that matters"
  
  This is a reland of commit 61728827d2e5ecce685578bc54bb2c744b65fc9a
  
  Changes made on top of previous commit
  1. In src/program_serialize_data_version.py,
  fix the script error on Windows: anglebug.com/7918.
  2. In BUILD.gn, replace the 'write_file' with
  'response_file_content'. See
  https://gn.googlesource.com/gn/+/main/docs/reference.md#var_response_file_contents
  3. In scripts/generate_android.bp.py, add code to
  handle the special GN build flag {{response_file_name}}.
  The code writes the list defined in srcs
  (identified by $(in) in Android blueprint) into a
  temp file named 'gn_response_file', and replaces the
  {{response_file_name}} with 'gn_response_file'.
  
  Original change's description
  
  > Changes made on top of original commit
  > 1. Enable execution permission on python script
  > program_serialize_data_version.py
  > 2. Remove unused list in libGLESv2.gni
  > 3. In angle/BUILD.gn, change file path from
  > "relative to angle_root", to "relative to root_build_dir",
  > so that inside the script program_serialize_data_version.py,
  > we don't have to find the absolute path of the code files for
  > hashing.
  
  > Original change's description
  
  > > 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.
