Unify the format of wit files

[oovm]

I wrote a tool that does project-level formatting: https://plugins.jetbrains.com/plugin/24001-wit-idl

Also respects the rules defined in the .editorconfig file.

The current code style is a bit confusing.

Most file use a mixture of 2 and 4 spaces, some files use 6 spaces, and one uses 7 spaces.

This PR makes all wit files have a unified code style which defined in .editorconfig.

Changes will be synchronized to other upstreams later.

Projects with 0.3.0-draft wit still need some additional development work.

IIUC these are mirrors of upstream files?

Would it make sense instead to apply these changes upstream first, to avoid have large downstream differences?

Thanks for this! These are just mirrors although I don't have an issue with normalizing what we have here while also updating upstream. For the individual proposal repos, we need to also have this run as a lint like we do with wit-abi-up action.
