mesa/glsl: Add support for NV_shader_noperspective_interpolation

Browse Source 
With EXT_gpu_shader4 the support is already in place, we just
have to allow it in glsl and expose the extension name.

v2: Check whether the extension is enabled in the shader (Adam Jackson)
v3: Don't check GLES version in lexer (mareko)
