gfx/rs90: Optimise layout of sdl_rs90_video

Browse Source 
Move frequently accessed member variables to the beginning of the
structure to improve cache locality. Having menu_texture at the end of
the structure also saves one instruction in the hot path of
sdl_rs90_gfx_frame() (for the ARMv5TE Miyoo) as well as a few other
functions.
