experiment: wgpu sync

[AaronO]

An experiment to streamline keeping our ext/webgpu in sync with upstream gfx-rs/wgpu

TODO

• gfx-rs/wgpu doesn't have lib.deno_webgpu.d.ts or deno_webgpu::get_declaration() fix(deno_webgpu): add TS type declarations gfx-rs/wgpu#2402
• Maintain the TS bindings ourselves outside of wgpu's deno_webgpu tree
• Sync indexmap versions (we use 1.7.0, https://github.com/gfx-rs/naga uses 1.6.0 if using wgpu tip)
• Bump naga dep in wgpu-core to resolve indexmap mismatch chore: bump naga to a1840be gfx-rs/wgpu#2401
• chore(deno_webgpu): bump deno crates gfx-rs/wgpu#2405
• lint: deno_webgpu & wgpu-core gfx-rs/wgpu#2403

A README on how to upgrade these crates would be useful

A README on how to upgrade these crates would be useful

Simply:

1. Change COMMIT in ./tools/wgpu_sync.js
2. Run ./tools/wgpu_sync.js
3. Double check changes, possibly patch

Great, but if there's no README then it will be lost.

Yeah I'll add it, with some other polish. This started out mainly as an experiment to PoC it and avoid fragmenting deno_core and splitting it out of the repo if not necessary

LGTM, just that README is missing
