Add binary releases via github actions

[jacksonrl]

Fixes https://issues.chromium.org/issues/409590665. See also https://issues.chromium.org/issues/409590665#comment6.

Here's an example of how the release would look: https://github.com/jacksonrl/dawn/releases/tag/v20251223.163459-jacksonrl.dawn.main The only difference is the name wouldn't have my name in it, which I think is autogenerated due to being a fork, and it would contain the macos/ios builds as well, which I disabled in my local version when testing due to low balance for macos runners (diff: jacksonrl/dawn@7d88c22...e53c2d0)

There are some ways we could improve the release outputs, but I wanted to make as minimal changes as possible to prevent any breakage as I cannot test all these platforms. Therefore this just uploads the output from the existing CI, which is mentioned in 409590665. These are nightly releases so nobody is expecting them to be stable, we can always improve this later

This also fixes the emdawnwebgpu release which was broken by 0979968 by removing wgpuTextureGetTextureBindingViewDimension from the emdawnwebgpu header. I'm not too familiar with the codebase so someone should please check that that is valid.

Motivation: Many people end up needing graphics at some point. Having prebuilt binaries allows people to choose WebGPU more readily, which strengthens the WebGPU ecosystem (eg. more libraries made with wglsl) and also allows people to potentially port their code to web at a later point.
