Remove rust-analyzer from rust package

Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

rust-analyzer takes up ~37MB (~4% of the package size) and follows its own update schedule, receiving updates more frequently than the main Rust release cycle. Since it's not required for standard Rust compilation, it should not be bundled with the core toolchain.

This change:

• Removes rust-analyzer binary and manifest from the rust package
• Adds tests to verify rust-analyzer is not present

Closes #270

@conda-forge-admin, please rerender

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ Use of posix package on windows is deprecated. Use m2-base.
• ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

Hi! This is the friendly automated conda-forge-webservice.

I tried to rerender for you, but it looks like there was nothing to do.

This isn't quite working as intended on Windows — the PR contains no change to install-rust.bat, but it appears that the rust-analyzer pieces are named rust-analyzer-preview and installed under different names such that the Windows check added in meta.yaml succeeds nonetheless. We should update install-rust.bat to properly remove the analyzer bits and fix the check in meta.yaml.

There is some black magic trickery that simply invokes install_rust.sh on windows and sets %PREFIX% to be %PREFIX%/Library. If you check the build output you will see the files are not include anymore.

Doing so I noticed that the pdb is still there. I removed that now as well.

Please move rust-analyzer to a separate output instead of just outright deleting it.
