Description of the new feature/enhancement

Currently the window title, as seen in the taskbar button, and window titlebar if "showTabsInTitleBar" is set to false, are always the same as the tab title for the current tab,

This would allow those two to differ.

The intended use case would be to set a short title for a tab, e.g. "PS" for PowerShell, while allowing the application title to show as the window title, where it might contain the current path, e.g. "PS C;\Users\username"

Proposed technical implementation details (optional)

This will require a new setting "suppressApplicationTitleInTab" that would have a similar effect to the current "suppressApplicationTitle", but instead of altering both the tab title and window title as the current setting does, it would only force tabTitle into the tab.

Notes

I've already been working on this, and have a branch in my fork of this repo that has a working implementation. However, before I create a PR, I'd like to run the idea past the team, so that they can look it over and give a final go/no-go decision.

If you want to see it in action, fork my repo: https://github.com/dgnuff/terminal and take a look at branch features/title, 868e39e .
