mesa-snapshot: update to 25.2.0-rc2

Major changes include support for non-power-of-two (RGB/BGR 888) support
and compute shader fixes in turnip.

Drop 35316.patch, those commits are mostly merged now.

-+
-+This enables the rendering of RGB/BGR 24-bit format buffers directly
-+onto the framebuffer. For RGB888, support already exists for vertex and
-+texture formats, so render buffer format support has been added. For
-+BGR888, support for vertex, texture, and render buffer formats has been
-+added. The internal format chosen for both RGB888 and BGR888 is GL_RGB8.
