James Price 6b1e5f552b wgsl: Do not require a semicolon after a struct
Don't generate them either, which generated a lot of test churn.

Ben Clayton 9021eb5594 resolver: Allow parameters to shadow globals
In https://dawn-review.googlesource.com/c/tint/+/62444 the Resolver validated that there are no parameters of the same function with the same name, but this also introduced validation that errors if parameters shadow a module-scope variable.

The WGSL spec allows for shadowing, but Tint so far has not implemented this support.

There are transforms that generate functions that presume parameter <-> module-scope variable shadowing is okay. DecomposeMemoryAccess is one of these.

This fixes those transforms which could generate programs that fail validation.
