feat(avs-api): Add more AVS file system related functions

Browse Source 
These were previously missing and are required for
various file system related tasks such as iterating
directory trees, reading and writing files through
the AVS file system for the upcoming launcher
rework.

Note that the AVS API broke with some mode flags
after version 2.13.06.
