gallium: add TGSI_SEMANTIC_TEXCOORD,PCOORD v3
This makes it possible to identify gl_TexCoord and gl_PointCoord
for drivers where sprite coordinate replacement is restricted.
The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings
should be hidden behind the GENERIC semantic or not.
With this patch only nvc0 and nv30 will request that they be used.
v2: introduce a CAP so other drivers don't have to bother with
the new semantic
v3: adapt to introduction gl_varying_slot enum
