This CL adds a fuzzer for the audio processing module that exercises the handling of all user input sample rates logged by the UMA histogram WebAudio.AudioContext.HardwareSampleRate.
The fuzzer inherits a lot of structure from the audio_processing_configs_fuzzer, but is greatly simplified and therefore the only shared code is test::FuzzDataHelper.
Tested: Modified the build to explicitly trigger resampling issue and verified it exercises the code, then let an unmodified fuzzer run locally over the weekend without finding issues.
