feat(windows): report executable files

[CarterLi]

$PATHEXT is an Environment Variable that stores a list of the file extensions for operation system to execute. A file is considered executable if its extension matches $PATHEXT

FreeBSD tests are failing due to clippy issues that this PR among other things fixes: #1327

I rebased main and thus also added a fix for the FreeBSD pipeline ... CI should be green now.

This seems like a definite improvement over the current behavior, thanks!

OnceLock shouldn't incur a performance penalty if I remember correctly, right? ... Have you validated that? I don't have Windows, so I can't test it. On Linux I would've done something like this:

cargo build --release && hyperfine -w 500 -r 500  '{cmd} -l /usr/bin' --parameter-list cmd ./target/release/eza,eza --time-unit microsecond -N

[CarterLi]

I replaced OnceLock for Lazy, which can be further replaced for LazyLock as stated here, because the official document seems prefer LazyLock in simple cases

As for performance, I don't see much difference. As Windows I/O performance is bad comparing to *nix ( with antivirus running the performance is even MUCH worse ), I/O is always the bottleneck.
