glsl: Move UsesClipDistance from gl_{vertex,geometry}_program into gl_program.

This will make it easier for back-ends to share code between geometry
shader and vertex shader compilation.  Also, it is renamed to
"UsesClipDistanceOut" to clarify that (a) in geometry shaders, it
refers to the gl_ClipDistance output rather than the gl_ClipDistance
input, and (b) it is irrelevant in fragment shaders.
