gpu_fuzzer: cache shader translators

gpu_fuzzer: cache shader translators

The shader translators are basically stateless, but they get recreated (a costly
operation) for every new decoder.
Just keeping a reference to them is enough to keep them in the shader translator
cache, so introduce a getter for them in the decoder, and keep a reference to
them in the fuzzer code.
