Revert "Add support of auto folded directories" (zed-industries#8476)

Reverts zed-industries#7674

@ABckh: reverting this as it introduced a significant performance
slowdown, most likely caused by iterating through all the snapshot
entries to determine whether a directory is foldable/unfoldable/omitted.
It would be great if you could open a new PR that reverts this revert
and addresses the performance issues. Thank you!

Add :tabonly and :only vim commands (zed-industries#8337)

Release Notes:

- Added
[`:tabo[nly][!]`](https://neovim.io/doc/user/tabpage.html#%3Atabonly),
closes all the tabs except the active one but in the current pane only,
every other split pane remains unaffected.
The version with the `!` force closes the tabs while the one without
asks you to save or discard the changes.
- Added [`:on[ly][!]`](https://neovim.io/doc/user/windows.html#%3Aonly),
closes all the tabs *and* panes except the active one.
The version with the `!` force closes the tabs while the one without
asks you to save or discard the changes.
Since Zed does not have different splits per tab like in Neovim `:only`
works the same as it does in VscodeVim.
