Henrik RydgårdandClaude Opus 5.5 fa3eff96fb Display: Don't read past memory presenting a framebuffer from RAM

The PSP accepts display strides that run past the end of VRAM, and
negative ones (setframebuf.expected has -64 and 2048), and presenting
straight from memory read all 272 rows of whatever stride was set.
Without a matching framebuffer, that's a read far outside PSP memory.
Now the whole image has to be in memory, or the display shows black, on
the hardware backends and the software renderer.

A savestate's display framebuffer with an address outside RAM and VRAM,
or an invalid format, turns the display off instead.
