  [WGSL] Add code generation for textureSampleLevel

Reviewed by Mike Wyrzykowski.

Add the Metal code generation for textureSampleLevel, similar to the regular
textureSample function, just marginally more complicated as it needs the `level()`
wrapper around the level argument.

(WGSL::Metal::visitArguments):
(WGSL::Metal::emitTextureSampleLevel):
(WGSL::Metal::FunctionDefinitionWriter::visit):
