gpu: Preserve first-frame font render targets
...
Some games render HLE sceFont glyphs into small VRAM-backed framebuffers and immediately sample them as textures. This needs both the source glyph buffer and the temporary render target to be preserved before later commands overwrite or rebind them.
Save first-frame data from the previous render target before creating a new framebuffer, since ResizeFramebufFBO() makes the new framebuffer current. Also flush pending draws before PGF writes over a glyph buffer that may still be referenced by queued texture draws.
Backend software transform normally reports safe framebuffer size during draw flush, but first-frame readback can happen before queued draws reach that path. Estimate through-mode rectangle/triangle bounds before SubmitPrim() and feed those bounds to SetSafeSize(), using actual vertices clamped to scissor instead of a tiny-target heuristic.
Fixes missing text in Evangelion JO.
