BuiltIns / Entrypoint input variables / FunctionArgs do not have a name in glsl-in #5422
Description
This was originally written as #5417 but upon investigation this issue was found.
The glsl frontend does not include the builtin name when synthesizing FunctionArgs for each EntryPoint. My rust backend would like to rename the variable name rather than hardcode a mapping between BuiltIns and the desired name.
This PR should be reopened if this issue is valid: #5418
