Remember window restore size (#10429)
Now, regardless of how the Zed window is closed, Zed can remember the
window's restore size.

- [x] Windows implementation
- [x] macOS implementation
- [x] Linux implementation (partial)
- [x] update SQL data base (mark column `fullscreen` as deprecated)

The current implementation on Linux is basic, and I'm not sure if it's
correct.

The variable `fullscreen` in SQL can be removed, but I'm unsure how to
do it.
edit: mark `fullscreen` as deprecated

### Case 1

When the window is closed as maximized, reopening it will open in the
maximized state, and returning from maximized state will restore the
position and size it had when it was maximized.

### Case 2

When the window is closed as fullscreen, reopening it will open in
fullscreen mode, and toggling fullscreen will restore the position and
size it had when it entered fullscreen (note that the fullscreen
application was not recorded in the video, showing a black screen, but
it had actually entered fullscreen mode).

### What's more

- As English is not my native language, some variable and struct names
may need to be modified to match their actual meaning.
- I am not familiar with the APIs related to macOS and Linux, so
implementation for these two platforms has not been done for now.
- Any suggestions and ideas are welcome.
