Stephen White 46647f1c13 GLSL: put std430 packing on all buffer variables. 
This is not 100% correct (the exceptions for mat2 and friends are not
implemented yet), but gets more tests passing in Dawn.

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 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.
