[WGSL] Add code generation for all synchronization built-in functions
https://bugs.webkit.org/show_bug.cgi?id=262304
rdar://116179474
Reviewed by Mike Wyrzykowski.
Add code generation for storageBarrier, workgroupBarrier and
workgroupUniformLoad.
The last one requires detecting whether the program actually uses it in order to
emit a helper, which is currently quite hacky, but we don't have a proper way of
tracking whether the built-ins are being called (or a function that shadows
them),
so that will be improved on a later patch.
