Gaauwe Rombouts a852bcc094 Improve system window tabs visibility (#37244)
Follow up of https://github.com/zed-industries/zed/pull/33334

After chatting with @MrSubidubi we found out that he had an old defaults
setting (most likely from when he encountered a previous window tabbing
bug):
```
❯ defaults read dev.zed.Zed-Nightly
{
    NSNavPanelExpandedSizeForOpenMode = "{800, 448}";
    NSNavPanelExpandedSizeForSaveMode = "{800, 448}";
    NSNavPanelExpandedStateForSaveMode = 1;
    NSOSPLastRootDirectory = {length = 828, bytes = 0x626f6f6b 3c030000 00000410 30000000 ... dc010000 00000000 };
    "NSWindow Frame NSNavPanelAutosaveName" = "557 1726 800 448 -323 982 2560 1440 ";
    "NSWindowTabbingShoudShowTabBarKey-GPUIWindow-GPUIWindow-(null)-HT-FS" = 1;
}
```

> That suffix is AppKit’s fallback autosave name when no tabbing
identifier is set. It encodes the NSWindow subclass (GPUIWindow), plus
traits like HT (hidden titlebar) and FS (fullscreen).

Which explains why it only happened on the Nightly build, since each
bundle has it's own defaults. It also explains why the tabbar would
disappear when he activated the `use_system_window_tabs` setting,
because with that setting activated, the tabbing identifier becomes
"zed" (instead of the default one when omitted) for which he didn't have
the `NSWindowTabbingShoudShowTabBarKey` default.

The original implementation was perhaps a bit naive and relied fully on
macOS to determine if the tabbar should be shown. I've updated the code
to always hide the tabbar, if the setting is turned off and there is
only 1 tab entry.

While testing, I also noticed that the menu's like 'merge all windows'
wouldn't become active when the setting was turned on, only after a full
workspace reload. So I added a setting observer as well, to immediately
set the correct window properties to enable all the features without a
reload.

Release Notes:

Gaauwe RomboutsandConrad Irwin 78c2f1621d Add macOS window tabs (#33334)
Closes https://github.com/zed-industries/zed/issues/14722
Closes https://github.com/zed-industries/zed/issues/4948
Closes https://github.com/zed-industries/zed/issues/7136

Follow up of https://github.com/zed-industries/zed/pull/20557 and
https://github.com/zed-industries/zed/pull/32238.

Based on the discussions in the previous PRs and the pairing session
with @ConradIrwin I've decided to rewrite it from scratch, to properly
incorporate all the requirements. The feature is opt-in, the settings is
set to false by default. Once enabled via the Zed settings, it will
behave according to the user’s system preference, without requiring a
restart — the next window opened will adopt the new behavior (similar to
Ghostty).

I’m not entirely sure if the changes to the Window class are the best
approach. I’ve tried to keep things flexible enough that other
applications built with GPUI won’t be affected (while giving them the
option to still use it), but I’d appreciate input on whether this
direction makes sense long-term.

### Features
* System-aware tabbing behavior
* Respects the three system modes: Always, Never, and Fullscreen
(default on macOS)
* Changing the Zed setting does not require a restart — the next window
reflects the change
* Full theme support
    * Integrates with light and dark themes
* [One
Dark](https://github.com/user-attachments/assets/d1f55ff7-2339-4b09-9faf-d3d610ba7ca2)
* [One
Light](https://github.com/user-attachments/assets/7776e30c-2686-493e-9598-cdcd7e476ecf)
    * Supports opaque/blurred/transparent themes as best as possible
* [One Dark -
blurred](https://github.com/user-attachments/assets/c4521311-66cb-4cee-9e37-15146f6869aa)
* Dynamic layout adjustments
    * Only reserves tab bar space when tabs are actually visible
* [With
tabs](https://github.com/user-attachments/assets/3b6db943-58c5-4f55-bdf4-33d23ca7d820)
* [Without
tabs](https://github.com/user-attachments/assets/2d175959-5efc-4e4f-a15c-0108925c582e)
* VS Code compatibility
* Supports the `window.nativeTabs` setting in the VS Code settings
importer
* Command palette integration
    * Adds commands for managing tabs to the command palette
* These can be assigned to keyboard shortcuts as well, but didn't add
defaults as to not reserve precious default key combinations

Happy to pair again if things can be improved codewise, or if
explanations are necessary for certain choices!



Release Notes:
* Added support for native macOS window tabbing. When you set
`"use_system_window_tabs": true`, Zed will merge windows in the same was
as macOS: by default this happens only when full screened, but you can
adjust your macOS settings to have this happen on all windows.
