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.
