editor: Add "Wrap Selections in Tag" action (#36948)

Browse Source 
This PR adds the ability for a user to select one or more blocks of text
and wrap each selection in an HTML tag — which works by placing multiple
cursors inside the open and close tags so the appropriate element name
can be typed in to all places simultaneously.

This is similar to the emmet "Wrap with Abbreviation" functionality
discussed in #15588 but is a simpler version that does not rely on
Emmet's language server.

Here's a preview of the feature in action:


https://github.com/user-attachments/assets/1931e717-136c-4766-a585-e4ba939d9adf


Some notes and questions:
- The current implementation is a hardcoded with regards to supported
languages. I'd love some direction on how much of this information to
push into the relevant language structs.
- I can see this feature as something that languages added by an
extension would want to enable support for — is this something you'd
want?
- The syntax is hardcoded to support HTML/XML/JSX-like languages. I
don't suppose this is a problem but figured I'd point it out anyway.
- I called it "Wrap in tag" but open to whatever naming you feel is
appropriate.
- The implementation doesn't use `manipulate_lines` — I wasn't sure how
make use of that without extra overhead / bookkeeping — does this seem
fine?
- I could also investigate adding wrap in abbreviation support by
communicating with the Emmet language server but I think I'll need some
direction on how to handle Emmet's custom LSP message. I could do this
either in addition to or instead of this feature — though imo this
feature is a nice "shortcut" regardless.

Release Notes:

- Added a new "Wrap Selections in Tag" action that lets you wrap one or
more selections in tags based on language. Works in HTML, JSX, and
similar languages, and places cursors inside both opening and closing
tags so you can type the tag name once and apply it everywhere.
