Fuzz APM sample rates

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.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
