mesa: Add the remaining from/to types for GL_EXT_texture_integer (and R/RG).

This aborts and crashes in intel oglconform's int-textures into being
just rendering failures.  Clamping isn't handled yet.

v2: Add missing "break".
v3: Drop the int/uint distinction, since they don't need different clamping.
NOTE: This is a candidate for the 8.0 branch.
