Other shader types don't need this.
Also fix code style of member var.

Move builtin_to_string() and builtin_type() to
the CanonicalizeEntryPointIO transform. Use the former to
rename entry point IO variables to the gl_ names, and the latter
to cast values to the correct type.

More line() and less std::endl.
More automated indents and less manual spacing.
Put a single newline after every struct and function declaration.
Note that this does touch every test result, but only affects whitespace.

This transform converts all separate texture/sampler references
in a program into combined texture/samplers. This is required for GLSL,
which does not support separate texture/samplers.
As input, the transform requires a map from the unique sampler/texture
pairs previously gathered by the Resolver to strings, which will be
used as the names of the newly-generated combined samplers. Note that
binding points are unused by GLSL, and so are set to (0, 0) with
collision detection disabled.
All function signatures containing textures or samplers are rewritten,
as well as function calls and texture intrinsic calls. For texture
intrinsic calls, a placeholder sampler is used to satisfy the subsequent
Resolver pass (GLSL texture intrinsics do not require a separate sampler,
but WGSL intrinsics do). The placeholder is also used if the shader
contains only texture references (e.g., textureLoad).
