Update WebGPU headers (emscripten-core#16078)

* Update WebGPU to dawn a83c434cc785ea55fc9e76f055522378e32bf199

* fix reference_struct_info.json

* Update dawn generator headers with 'upstream' tags; Fix power preference undefined

* add depth clip control feature name

* some library_webgpu.js implementation

* check map size with uint32

* test_gen_struct_info rebaseline

* add back some upstream only functions

* update webgpu readme

* map size check against -1
