This adds the ability for Zed to restore unsaved buffers on restart. The
user is no longer prompted to save/discard/cancel when trying to close a
Zed window with dirty buffers in it. Instead those dirty buffers are
stored and restored on restart.
It does this by saving the contents of dirty buffers to the internal
SQLite database in which Zed stores other data too. On restart, if there
are dirty buffers in the database, they are restored.
On certain events (buffer changed, file saved, ...) Zed will serialize
these buffers, throttled to a 100ms, so that we don't overload the
machine by saving on every keystroke. When Zed quits, it waits until all
the buffers are serialized.
### Current limitations
- It does not persist undo-history (right now we don't persist/restore
undo-history regardless of dirty buffers or not)
- It does not restore buffers in windows without projects/worktrees.
Example: if you open a new window with `cmd-shift-n` and type something
in a buffer, this will _not_ be stored and you will be asked whether to
save/discard on quit. In the future, we want to fix this by also
restoring windows without projects/worktrees.

### Related tickets
I'm unsure about closing them, without also fixing the 2nd limitation:
restoring of worktree-less windows. So let's wait until that.

- https://github.com/zed-industries/zed/issues/4683
### Note on performance
- Serializing editing buffer (asynchronously on background thread) with
500k lines takes ~200ms on M3 Max. That's an extreme case and that
performance seems acceptable.
Release Notes:
- Added automatic restoring of unsaved buffers. Zed can now be closed
even if there are unsaved changes in buffers. One current limitation is
that this only works when having projects open, not single files or
empty windows with unsaved buffers. The feature can be turned off by
setting `{"session": {"restore_unsaved_buffers": false}}`.

When running the tests for linux, I found a lot of benign errors getting
logged. This PR cuts down some of the noise from unnecessary workspace
serialization and SVG renders

This PR adds a new `cargo xtask licenses` command for finding crates
with missing license files.
A number of crates were uncovered that were missing a license file, and
have had the appropriate license file added.

The new `ElementContext` was originally introduced to ensure the element
APIs could only be used inside of elements. Unfortunately, there were
many places where some of those APIs needed to be used, so
`WindowContext::with_element_context` was introduced, which defeated the
original safety purposes of having a specific context for elements.
This pull request merges `ElementContext` into `WindowContext` and adds
(debug) runtime checks to APIs that can only be used during certain
phases of element drawing.

This PR implements the preview tabs feature from VSCode.
More details and thanks for the head start of the implementation here
#6782.
Here is what I have observed from using the vscode implementation ([x]
-> already implemented):
- [x] Single click on project file opens tab as preview
- [x] Double click on item in project panel opens tab as permanent
- [x] Double click on the tab makes it permanent
- [x] Navigating away from the tab makes the tab permanent and the new
tab is shown as preview (e.g. GoToReference)
- [x] Existing preview tab is reused when opening a new tab
- [x] Dragging tab to the same/another panel makes the tab permanent
- [x] Opening a tab from the file finder makes the tab permanent
- [x] Editing a preview tab will make the tab permanent
- [x] Using the space key in the project panel opens the tab as preview
- [x] Handle navigation history correctly (restore a preview tab as
preview as well)
- [x] Restore preview tabs after restarting
- [x] Support opening files from file finder in preview mode (vscode:
"Enable Preview From Quick Open")
I need to do some more testing of the vscode implementation, there might
be other behaviors/workflows which im not aware of that open an item as
preview/make them permanent.
Showcase:
https://github.com/zed-industries/zed/assets/53836821/9be16515-c740-4905-bea1-88871112ef86
TODOs
- [x] Provide `enable_preview_tabs` setting
- [x] Write some tests
- [x] How should we handle this in collaboration mode (have not tested
the behavior so far)
- [x] Keyboard driven usage (probably need workspace commands)
- [x] Register `TogglePreviewTab` only when setting enabled?
- [x] Render preview tabs in tab switcher as italic
- [x] Render preview tabs in image viewer as italic
- [x] Should this be enabled by default (it is the default behavior in
VSCode)?
- [x] Docs
Future improvements (out of scope for now):
- Support preview mode for find all references and possibly other
multibuffers (VSCode: "Enable Preview From Code Navigation")
Release Notes:
- Added preview tabs

Absent some ability to toggle between viewing and editing a file, I
think it would be best to get a fix out quick for people to edit SVGs as
text files.
Release Notes:
- Fixed editing of SVG images by disabling it from the image viewer
([#10403](https://github.com/zed-industries/zed/issues/10403)).
- Fixed#8603
For the label title of the project panel, I find that there is no place
to use to get the title of the label to do some operations, it should be
safe to modify it, but I'm not sure how we need to modify the problem, I
can think of two scenarios:
1. Modify every place where you don't want multiple lines to appear
2. Make the label only display a single line (e.g. provide a new
parameter, or a new label type?)
While working towards fixes for the image viewer, @mikayla-maki and I
discovered that we didn't have `object-fit: scale-down` implemented.
This doesn't _fully_ solve the image issues as there is some issue where
only the bounds width is updating on layout change that I haven't fully
chased down.

This is a follow up to #9436 . It has a cleaner API and generalized the
image_cache to be a generic asset cache, that all GPUI elements can make
use off. The changes have been discussed with @mikayla-maki on Discord.
