Add ability to hide status bar (#39430)

This pull request adds the ability to configure the setting to hide or
show the status bar, as described in discussion:
https://github.com/zed-industries/zed/discussions/38591

The original [PR
#38974](https://github.com/zed-industries/zed/pull/38974#issuecomment-3362020879)
was merged but reverted due to hidden conflicts. As per @ConradIrwin 's
[request](https://github.com/zed-industries/zed/pull/38974#issuecomment-3362020879),
I am recreating the PR on top of updated main branch.

Release Notes:

- Added an experimental setting `"status_bar": { "experimental.show":
false}` to hide the status bars.
