As mentioned in https://github.com/microsoft/terminal/issues/9354#issuecomment-790034728
`GETSET_SETTING` is too visually similar to `GETSET_PROPERTY`, but with a _VERY_ different meaning. I think that merely changing the name of the macro would make it harder for us to make this mistake again.
## Summary of the Pull Request
After rename ends (either by enter or escape) the rename box
gets collapsed and the focus moves to the next tab stop
in the TabView (e.g., new tab button).
To overcome this:
* Added RenameEnded event to TabHeaderControl
* Forwarded it as RenamerDeactivated from TerminalTab
* Registered in the TerminalPage to focus the active control upon
RenamerDeactivated if focus didn't move to tab menu.
This means, no matter how you close the renamer,
the current terminal gains the focus.

1. Fix progress value not updated
2. Introduce TabStatus object and bind both TabHeaderControl and CommandPalette to it
3. Add support for read-only mode indicator
## Summary of the Pull Request
Introduces read-only panes.
When pane is marked as read-only:
1. Attempt to provide user input results in a warning
2. Attempt to close pane - shows dialog
3. Attempt to close hosting tab shows dialog
4. The hosting tab has no close button

## Detailed Description of the Pull Request / Additional comments
1. The readonly logic implemented in `TermControl`
(and prevents any send input)
2. Special handling is required to allow key-bindings
3. The "close-readonly" protections are in TerminalPage.
4. The indication that the pane is readonly is done using lock glyph
5. The indication that the tab contains readonly pane
is done by hiding the close button of the tab
6. The readonly mode is enabled by keyboard shortcut
(the followup might add this to the context menu)
## Validation Steps Performed
When we emit a BEL (visual or audible), show an indicator in the tab
header
If the tab the BEL is coming from is not focused when the BEL is raised,
the indicator in its header will be removed when the tab gains focus. If
the tab was already focused when the BEL was emitted, then the indicator
goes away after 2 seconds.
Closes#8106
Basically, just impose a height on both the renamer box and the overall
tab header control. However, to ensure that the text in the tab renamer
box does not get clipped by its own border, we also need to set its font
size, which is slightly smaller than it was before but it _is_ the same
as the text block that it is trying to rename so I'd say its more
consistent now.
We also improve the tab renamer box so that it scrolls as more text is
added instead of getting truncated (when the tabWidthMode is anything
other than titleLength). When the tabWidthMode _is_ set to titleLength,
the renamer box can increase in length much more (see GIFs below).
Closes#8519
This commit adds a [progress ring] to the tab header when we receive an
OSC 9 sequence.
Adds an event handler in `Tab.cpp` for the event we raise when we get a
request to set the taskbar state/progress. This event handler updates
the tab header with the active control's state/progress.
When we want to show the progress ring, we hide the tab icon and place
the progress ring over it.

Fix for #8365
Adds a `_renameCancelled` bool that determines whether we raise the event for a title change. We do this because the lost focus handler for the rename box will be called _both_ when the renamer is dismissed by clicking somewhere else and by pressing enter/escape. So, the lost focus handler needs to conditionally raise the event.
Closes#8365
