Description

WebGL has numerous issues with Index buffers being funky to use correctly, which necessitates various workarounds and nuance in the code dealing with copies. This is exemplified by #3157 but there is additional nuance.

https://github.com/gfx-rs/wgpu/blob/master/wgpu-hal/src/gles/queue.rs#L268-338 is the link to the buffer-to-buffer implementation.

Getting this working is also predicated on having our tests run in the browser.

Contributor guide

Research direction
Examine the buffer to buffer implementation in wgpu hal/src/gles/queue.rs and understand the workaround for WebGL index buffers. Ensure tests run in browser.
