Add option to switch file line endings (LF / CRLF) like in VSCode

[CreatorHell]

Hi!
Currently Zed doesn't seem to support switching the line ending format (LF vs. CRLF) for files, which is a feature that many editors like VSCode provide (e.g. in the status bar at the bottom right).

This feature is quite useful when working on cross-platform projects, or collaborating with people who use different systems.
It would be great if Zed could display the current file's line ending (LF or CRLF), and allow us to easily change it -- for example, via a status bar picker or via a command pallet command.

Feature request summary:

Show current file's line ending style (LF or CRLF) somewhere accessible in the UI (e.g., status bar).
Allow switching between LF and CRLF line endings for the current file.
Optionally, allow changing line endings for multiple files or by default (project setting).
Thanks a lot for your work on Zed!
