📄 Description

It turns out that the negative margin for the progress ring is causing
the clipping in case the tab title gets too long:

43dbbd590f/src/cascadia/TerminalApp/TabHeaderControl.xaml (L18-L27)

The negative margin was introduced in #8113 because the progress ring is
supposed to replace the tab icon but the TabView still reserves space
even if no icon is set (see
https://github.com/microsoft/terminal/pull/8133#issuecomment-739098014).
However, it is not actually the TabView reserving space even when
there is no icon, but a workaround for a crash in the
IconPathConverter that returns a BitmapIconSource with a nullptr
source instead of a nullptr IconSource:

43dbbd590f/src/cascadia/TerminalSettingsModel/IconPathConverter.cpp (L143-L154)

The workaround in IconPathConverter could probably be removed as I did
not find any instance where it is still used in a way that could trigger
the mentioned crash, but I did not dare to just remove it as I do not
know enough about the code by far. Hence, I opted to just locally
instantiate the IconSource with a nullptr directly in TerminalTab.

Fixes #8910
