Auto merge of #17118 - Veykril:linked-rust-files, r=Veykril

feat: Allow rust files to be used linkedProjects

With this, script files become more usable as the user can at least add them manually to the linked projects, allowing them to be used "on the (manual) fly" without having to open a separate vscode window that only has files open and no folder.

Also makes build scripts work for them (though no proc-macros, for some reason the dylib field is not populated in the output)

+Copy-pasted from

+
+An action used to publish GitHub releases for `wasmtime`.
+
+As of the time of this writing there's a few actions floating around which
+perform github releases but they all tend to have their set of drawbacks.
+Additionally nothing handles deleting releases which we need for our rolling
+`dev` release.
+
+To handle all this, this action rolls its own implementation using the
+actions/toolkit repository and packages published there. These run in a Docker
+container and take various inputs to orchestrate the release from the build.
+
+More comments can be found in `main.js`.
+
+Testing this is really hard. If you want to try though run `npm install` and
+then `node main.js`. You'll have to configure a bunch of env vars though to get
+anything reasonably working.
