Update wgpu to v0.19.3 and unpin web-sys. (#12247)

This PR unpins `web-sys` so that unrelated projects that have
`bevy_render` in their workspace can finally update their `web-sys`.
More details in and fixes #12246.

* Update `wgpu` from 0.19.1 to 0.19.3.
* Remove the `web-sys` pin.
* Update docs and wasm helper to remove the now-stale
`--cfg=web_sys_unstable_apis` Rust flag.

---

Updated `wgpu` to v0.19.3 and removed `web-sys` pin.
