Add centered layout support (#9754)

Browse Source 
This PR implements the Centered Layout feature (#4685):
- Added the `toggle centered layout` action.
- The centered layout mode only takes effect when there's a single
central pane.
- The state of the centered layout toggle is saved / restored between
Zed restarts.
- The paddings are controlled by the `centered_layout` setting:

```json
"centered_layout": {
  "left_padding": 0.2,
  "right_padding": 0.2
}
```

This allows us to support both the VSCode-style (equal paddings) and
IntelliJ-style (only left padding in Zen mode).

Release Notes:

- Added support for Centered Layout
([#4685](https://github.com/zed-industries/zed/pull/9754)).
