Reviewed by Mike Wyrzykowski.

It's not valid according to the spec to have a struct with no fields. We make it a

* Source/WebGPU/WGSL/Parser.cpp:
(WGSL::Parser<Lexer>::parseStructure):
* Source/WebGPU/WGSL/tests/invalid/empty-struct.wgsl: Added.
* Source/WebGPU/WGSL/tests/invalid/redeclaration-reordering.wgsl:
