Various WebGPU fixes based on feedback. (#3554)

Browse Source 
* Unset BGFX_CAPS_VERTEX_ATTRIB_UINT10. Remove MSAA 2x.

* Use destroy instead of release for buffers, textures, and querysets.

* Disable robustness, lazy clear resources in release builds.

* No need to pass entry point when there is only one entry point.
