  [WGSL] Update keywords and reserved words

Reviewed by Dan Glastonbury.

Update the set of keywords and reserved words as defined by the spec in
https://www.w3.org/TR/WGSL/#keyword-summary and https://www.w3.org/TR/WGSL/#reserved-words
respectively. This removes a few keywords that we had that are not actually keywords
and adds a bunch of reserved words. For now, we keep the special treatment for the
`array` identifier, as more work is required to treat array types as regular parameterized
types.
