FrogGBA v0.4.0-rc.1

FrogGBA v0.4.0-rc.1 is a PSP-focused performance and stability prerelease with dynarec cache improvements, safer SMC handling, adaptive PSP-1000 ROM memory, and large-ROM support.

TL;DR:

• Faster Allegrex dynarec cache publication
• FIQ banking and SMC fixes
• Adaptive 32 MiB → 8 MiB ROM allocation
• Large-ROM paging tested with Pokémon Unbound
• Lower Mode 0 scanline overhead

Backported from @andymcca:

• FIQ register-bank fix (#185)
• Mode 0 affine-work skip (#216)

Kudos to @andymcca for the upstream gpsp fixes and performance work.
