  [WGSL] Add support for calls with simple built-in types

Reviewed by Myles C. Maxfield.

Allow function calls with simple built-in types (i.e. function-style cast) such
as `f32(x)`. The way we currently handle it is not great, since we treat type
names as keywords in the lexer, but all of this will have to be refactored soon
when we update the parser to solve the template ambiguity. For now, this unblocks
a few more CTS tests to pass.
