📄 Description

This PR is similar to #2807, attempting to emulate the libSceGnmDriver initialization behavior needed for NBA 2K18 (CUSA08500) to progress further.

Unlike my previous attempt, this time I perform the memory mapping after our Linker::LoadSharedLibraries call, which places the memory mapping after the early memory mappings seen in GFD engine games, fixing the regressions that occurred last time I tried doing this.

A better long-term solution would be to perform this mapping in libSceGnmDriver's HLE initialization, though moving any HLE module initialization this far into the game loading process would take a fairly sizable rework of our module loading logic from what I can tell.

Tests would be appreciated, as this could cause regressions.
