LibAudio+Userland: Remove Audio::LegacyBuffer
The file is now renamed to Queue.h, and the Resampler APIs with LegacyBuffer are also removed. These changes look large because nobody actually needs Buffer.h (or Queue.h). It was mostly transitive dependencies on the massive list of includes in that header, which are now almost all gone. Instead, we include common things like Sample.h directly, which should give faster compile times as very few files actually need Queue.h.
