Add support baseVertex for GPURenderPassEncoder

Hi!

It would be nice to have baseVertex support for the mesh.

WebGL 2 adds support for this using WEBGL_draw_instanced_base_vertex_base_instance but its support seems to be very low (less than 1%) here https://web3dsurvey.com/webgl2

If you focus on chromium-like browsers, they have support; this greatly speeds up the work with indexes, for example for the LOD system.

I see this:

My MacOS on latest Chrome does not expose this extension.

What data do you see?
