Stephen White 0b39270e01 GLSL: move entry point handling to CanonicalizeEntryPointIO transform.
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.

Stephen White e2f35ba8e0 GLSL: clean up GLSL output whitespace generation.
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.

Stephen White b1d2b84f7d GLSL: fix clip space mismatch in gl_Position.
OpenGL clips against [-w, w], while WebGPU uses [0, w]. The fix is to
modify gl_Position.z on output to match GLSL semantics. (This is the
same code used by SPIRV-Cross under the fixup_clipspace option.)

James Price c7c80c053d glsl: Always emit structures
Skipping those that are block-decorated is not correct, as
block-decorated structures can also have non-buffer usages. This is
even clearer now that WGSL has removed the block attribute.

Stephen White ae4487f3f9 GLSL: rename all identifiers prefixed with gl_.
In GLSL, all identifiers beginning with gl_ are reserved (not just those
explicitly named in the spec), and so any found in WGSL must be renamed.
