Implement GpuCompiler::LoadAutotuneResultsFromFile and GpuCompiler::SerializeAutotuneResultsToFile to support the new autotune cache format when xla_gpu_use_new_autotune_cache_format is enabled. When the flag is set: - Loading reads autotuner::AutotuneCache proto (binary or textproto) and populates InMemoryStore. - Dumping reads entries from InMemoryStore and serializes them to autotuner::AutotuneCache proto. Parameterize PersistedAutotuningTest in gpu_compiler_test to verify both legacy and new formats. PiperOrigin-RevId: 953447249
