Closes #51340
Release Notes:

- Linux/WSL: Added polling filesystem watching support in order to
support file watching on file systems that do emit events through
`inotify`, for example `/mnt/c` in WSL, network filesystems, and FUSE
mounts. Polling should be automatically chosen over `inotify` when
necessary, however it can be manually chosen by setting the
`ZED_FILE_WATCHER_MODE=poll` env var
