* Reinstates an allocator for FileCacheManager Replaces the allocator that was removed during redcode that is used for loading banks. Default schema for now to get things working again. * Update path functions to AZ::IO::Path Removes old PathUtil functions in favor of AZ::IO::Path apis. * Update the audio allocator classes Cleans up the audio allocator classes a bit. * Addresses PR feedback Updates some code to handle nullptr a bit better, and improve log messages. * Updates to audio CVars and address feedback Per feedback, converted more of the audio cvars to AZ_CVAR, but not all of them could be converted at this time. Moved audio allocator initialization to system component ctor/dtor to give RAII. Updated location of a PAL file. * Updates the copyright of the file added in this PR Merged copyright changes, so need to update new files.
