[WGSL] Add `role`s to structs and parameters to aid codegen
https://bugs.webkit.org/show_bug.cgi?id=251089
<rdar://problem/104602741>
Reviewed by Myles C. Maxfield.
Add a field to indicate what is the role of structs and parameters. That
helps with codegen as we can identify as if a struct or parameter was generated
for a specific purposed, e.g. to receive stage_in parameters. This extra
information
helps when choosing the right metal attributes during codegen.
