vmwgfx: Add boolean flags for different rendering modes

Basically we support three ways of getting data to the screen:
1) Mixed mode: We mix presents and updates.
2) Mixed present optimized: A version of mixed where copies to the front
   buffer end up as presents, saving a blit.
3) 3D surface mode: We only present from a 3D surface. Software contents are
   first DMA'd to that surface.

This change adds boolean flags to the saa struct to select which mode to use.
