[jak2] Add static textures for the progress menu (#2838)

The progress menu loads its icon textures from a .STR file that we were
previously ignoring.

This change:
- updates the decompiler so it can process a .STR file containing a
texture
- adds a feature to force an entire page to always be loaded in the PC
renderer by putting all textures in the GAME.FR3 file.
- regenerates the texture offset map file for jak 2 with these new
textures

For now, I've just put the icon textures in GAME.FR3. The downside is
that these will always stay on the GPU, using up VRAM even when they
aren't needed. But the entire GAME.FR3 file is under 3 MB so I think
it's ok.
