Fix include paths to support both vendored and system-installed glslang. Remove usage of the private `StandAlone` bits. Requires us to vendor a copy of `DefaultTBuiltInResource` (or provide our own customized one) as glslang doesn't provide it in its public API. Also removes unused C interface as it's not well encapsulated and depends on `StandAlone`. Fixes #56307.
