zed-zippy[bot] 3aef0f01b0 extension_host: Fix IS_WASM_THREAD being set for wrong threads (#43005) (cherry-pick to stable) (#43017)
Cherry-pick of #43005 to stable

----
https://github.com/zed-industries/zed/pull/40883 implemented this
incorrectly. It was marking a random background thread as a wasm thread
(whatever thread picked up the wasm epoch timer background task),
instead of marking the threads that actually run the wasm extension.

This has two implications:
1. it didn't prevent extension panics from tearing down as planned
2. Worse, it actually made us hide legit panics in sentry for one of our
background workers.

Now 2 still technically applies for all tokio threads after this, but we
basically only use these for wasm extensions in the main zed binary.

Release Notes:

- Fixed extension panics crashing Zed on Linux

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
