glsl/builtins: Rework profiles to use the new '.glsl' common suffix.
Deletes a lot of pointless duplication, as well as some run-time effort.
Conveniently, GLSL 1.40 no longer needs a .vert variant, since it
doesn't define any built-ins specific to the vertex shader stage.
ARB_texture_rectangle and OES_EGL_image_external also only need a single
profile, since the .vert and .frag variants were identical.
I didn't bother with EXT_texture_array and OES_texture_3D because
they're so tiny that the savings would be miniscule.
Cuts the generated builtin_function.cpp from 1.7MB to 1.0MB (41%).

glsl/builtins: Support stage-agnostic built-in profiles.
The built-in subsystem uses "profiles," or GLSL shaders containing
prototypes for all built-ins supported within a particular language
version (or extension) and shader stage.
Since profiles were stage-specific, we had to cut and paste almost all
the prototypes between (e.g.) 110.vert and 110.frag. Naturally, this
led to sundry cut and paste bugs, where someone fixed an issue in .frag
but neglected to update .vert, or vice-versa. Geometry shaders would
have only made this worse.
This patch introduces support for a new '.glsl' profile suffix which
contains prototypes common to all shader stages. The existing '.frag'
and '.vert' profiles need only contain the few stage-specific built-ins.
Not only does this remove duplication, it makes built-in setup slightly
faster: we don't need to re-read the common prototypes and function
bodies for both the vertex and fragment shader stage.
Internally, this was trivial. We already create a list of gl_shader
objects to search through for built-ins: one for the core language
version/stage, and additional shaders for any extensions in use. This
patch simply adds another shader to the list: core/common, core/stage,
and extensions.
The next patch will update the profiles to remove the duplication.
It's separated out purely to make review easier.

glsl/builtins: Use ivec for texel offsets in textureProjGradOffset.
The GLSL 1.30 -> 4.10 specs all erroneously say "vec2" for a few
overloads of textureProjGradOffset, while most overloads and all other
texturing functions use ivec types.
The GLSL 4.20 specification corrects these to "ivec2", but doesn't
mention this as being a conscious change in behavior. Nor does the
ARB_shading_language_420pack extension. So presumably it was a typo.
At any rate, our builtin functions all use ivec already, so the fact
that these prototypes use plain vecs will only lead to applications
dying in a fire when trying to use them.

"If the program object has no vertex shader, or no program object
