glsl: Create builtin function profiles for GLSL 3.00 ES.

Nearly all of the builtin functions in GLSL 3.00 ES are already
implemented in Mesa; this patch enables them.

A few functions are not implemented yet; those have been commented
out, with a FIXME comment to act as a reminder of what still needs to
be implemented.  Here is the complete list: packSnorm2x16,
unpackSnorm2x16, packUnorm2x16, unpackUnorm2x16, packHalf2x16,
unpackHalf2x16.
