* 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.
