language: Further optimize language_for_file (#28694)
Follow-up to #28671

This primarily follows two ideas:
1. We currently take the element with the highest score which appears
last in the iterator (see
[`last_by_key`](https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.max_by_key)),
so we can also just reverse the iterator and take the first highest
match instead.
2. Once we have a match with a given precedence, we are not interested
in any matches with a lower or even the same priority, given what was
established in 1. Thus, we also only have to check whether any language
checked afterwards has a higher priority match.

Furthermore, once we have a match with the highest possible precedence,
there is no need to look for any more possible matches. Thus, this PR
also adds short-circuiting for that scenario.

Lastly, I also cleaned-up the custom suffix match (an empty glob-set
will never match so no need to iterate there) as well reorder the
zip-call in the content matches, as we never need the content if there
is no first line pattern present for the checked languages.

Release Notes:

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.
