feat(lsp): drop fswatch, use inotifywait (#29374)

Browse Source 
This patch replaces fswatch with inotifywait from inotify-toools:

https://github.com/inotify-tools/inotify-tools

fswatch takes ~1min to set up recursively for the Samba source code
directory. inotifywait needs less than a second to do the same thing.

https://github.com/emcrisostomo/fswatch/issues/321

Also it fswatch seems to be unmaintained in the meantime.
