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.
