Backends, Examples: removed Emscripten < 4.0.10 support. Removed IMGUI_IMPL_WEBGPU_BACKEND_WGPU. (#9281, #8381)

Browse Source 
- This commit removes the option of using -sUSE_WEBGPU=1 from CMake and make
- Compiling with a version of Emscripten >= 4.0.10 will work the same way as it was before
- Compiling with a version of Emscripten < 4.0.10 will print an error message and abort the build (in the case of CMake)
- Since there can only be 1 implementation for the backend in the case of Emscripten, this commit cleans the code accordingly
