gallium: add scalar isa shader cap

v1 -> v2:
 - nv30 is _NOT_ scalar as suggested by Ilia Mirkin.
 - Change from a screen cap to a shader cap as suggested
   by Eric Anholt.
 - radeonsi is scalar as suggested by Marek Olšák.
 - Change missing ones to be scalar.

v2 -> v3:
 - r600 prefers vec4 as suggested by Marek Olšák.
