Rationalize File timestamp callback (#7785)

Browse Source 
Fixes #7775

Clean up the passing/setting of custom File time callbacks and add a
host test verifying they work.  Existing core was not passing custom
timeCallbacks set at the FS level down to open()ed files, resulting in
them calling the default time(nullptr) and reporting wrong file modify
times.
