nir: remove dependency on glsl

Move glsl_types into NIR, now that the dependency on glsl_symbol_table
has been split out.

Possibly makes sense to rename things at this point, but if we do that
I'd like to keep it split out into a separate patch to make git history
easier to follow (IMHO).

v2: fix android build
v3: I f***ing hate scons.. but at least it builds
