Kian Kasad e6214b2b71 extensions: Don't recompile Tree-sitter parsers when up-to-date (#43442)
When installing local "dev" extensions that provide tree-sitter
grammars, compiling the parser can be quite intensive[^anecdote]. This
PR changes the logic to only compile the parser if the WASM object
doesn't exist or the source files are newer than the object (just like
`make(1)` would do).

[^anecdote]: The tree-sitter parser for LLVM IR takes >10 minutes to
compile and uses 20 GB of memory on my laptop.

Release Notes:

- N/A

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.
