Graph GPUUISceneNewtDemo: Filter out all FSAA (multisample) caps if undesired (Graph VBAA + MSAA); Add NonFSAAGLCapabilitiesChooser

Notable: On RaspiPi4b w/ Mesa3D's Broadcom/VC driver,
the chosen capabilities is a multisamnple one even though not requested.

This causes
- extra performance overhead
- doubled AA: 1st our VBAA, then the FSAA (multisample) -> loss of sharpness

Simply dropping the undersired FSAA helps and ups performance
on the Raspi board (22 -> 35 fps).
