Add support for per-profile tab colors (#7162)
This PR adds support for per-profile tab colors, in accordance with
#7134. This adds a single `tabColor` property, that when set, specifies
the background color for profile's tab. This color can be overridden by
the color picker, and clearing the color with the color picker will
revert to this default color set for the tab.

* Full theming is covered in #3327 & #5772 

Validation: Played with setting this color, both on launch and via
hot-reload

Specified in #7134
Closes #1337
