Replaces many loops of the form:
```js
for (let i = 0; i < elements.length; ++i) {
const i = elements[i];
...
}
```
with:
```js
for (const element of elements) {
...
}
```
Mix of a horrible regex based find/replace and manual touch ups
* Allow Emmet "Go to matching pair" to work inside script tags
* Refactor template script detection and node extraction.
* Futher refactoring of Emmet template identification logic.
* Emmet: select entire script tag when unable to idnetify an inner element
* Remove redundant nullity check
* When wrapping using Emmet, don't consider lines with no characters selected.
* Adding unit tests
* Adding support for multicursors in wrapIndividualLinesWithAbbreviation
* Moving check in multicursor wrapIndividualLines
* Make sure when expanding several abbreviations with different snippets that the edits are applied in reverse order.
* Revert "Fix for Emmet's wrap with abbreviation inserting extra spaces (#43345)"
This reverts commit 7420a04c64.
* 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.
