* Revert "Fix for Emmet's wrap with abbreviation inserting extra spaces (#43345)"

This reverts commit 7420a04c.

* Adding ability for emmet to wrap with abbreviation in real time.

Currently it's only working for single cursor.

* Fixes to wrap in real time:

- Removed flickering when typing abbreviation
- Removed tabstops
- Fixed bug when wrapping multiline text

* Fixes to a few issues.

- Added checks for not reverting previews more times than needed, that was causing extra text to be deleted.
- Fixed issue when wrapping nodes with multiple level of indentation.
- Removed all the undo commands. Now all the logic of going back to the original state is handled by revertPreview.

* Ammend for previous revert

* Reapplying reverted commit, fixing the bug for this branch's version

Refactoring some of the code, now a single object contains the current and original ranges, as well as the original content to wrap

* Adding multicursor support

* Renaming, refactoring and other stuff

* More refactorings

* More renaming and refactoring

* Replacing placeholders when previewing, simplifying the extracting of preceeding whitespace, added a check for validity of expandedtext on each selection.

* More refactoring

* Adding a comment.

* Readding test removed by mistake.

* Refactoring

* Carefully reverting changes in yarn.lock

* carefully but right

These files depend on electron APIs such as webview. They should life in electron browser rather than browser

I believe that overflow is already handled by the webview itself
