Re-applies https://github.com/zed-industries/zed/pull/30840
This PR re-applies the initial
[PR](https://github.com/zed-industries/zed/pull/30840). As it was closed
because it was hard to land, because of the many conflicts. This PR
re-applies the changes for it.
In several cases we were creating multiple display_map
snapshots within the same root-level function call.
Creating a display_map snapshot is quite slow, and in some
cases we were creating the snapshot multiple times.
Release Notes:
- N/A
Before this change the active theme and icon theme were retrofitted onto
the ThemeSettings.
Now they're in their own new global (GlobalTheme::theme(cx) and
GlobalTheme::icon_theme(cx))
This lets us remove cx from the settings traits, and tidy up a few other
things along the way.
Release Notes:
- N/A
This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.

This PR adds `editor: diff clipboard with selection` - good for spotting
the differences in eerily-similar code, which is when refactoring code,
as you need to see what needs to be passed in in order to maintain
previous behavior of both snippets.
1. Copy some text from anywhere
2. Highlight some text in Zed
3. Run `editor: diff clipboard with selection`
Like JetBrains' IDEs and VS Code with the `PartialDiff` package, if the
selection is empty, we take the entire buffer as the selection.
Caveats:
- We do not know the language of the text in the clipboard. I went ahead
and just assumed that in most cases, it will be the same language as the
selected text, which does mean we will highlight the old text
incorrectly if they are copying from a different language, but I think
in most cases, it will be the same, and the alternative of always having
no syntax highlighting is worse. PyCharm seems to do the same thing.
Release Notes:
- Added an `editor: diff clipboard with selection` action
