Change the "FetchBuiltInCMap"/"FetchStandardFontData" message-handlers to be asynchronous

This way we can directly throw Errors, rather than having to "manually" return rejected Promises, which is ever so slightly shorter.

Also, since `useWorkerFetch` is always true in MOZCENTRAL builds these message-handlers should not be invoked there.
