Test: highlight modified tabs

[bpasero]

#26284

Complexity: 2

• anyOS @roblourens
• anyOS @weinand (macOS)

A new setting workbench.editor.highlightModifiedTabs allows to draw a (themable: tab.activeModifiedBorder etc. ) border to the top of tabs whenever they are dirty.

Verify:

• no border is drawn unless workbench.editor.highlightModifiedTabs is true
• when enabled a border is showing on top of the tab until you save
• even if the theme (or your settings) configure to draw a top border for a tab (via tab.activeBorderTop), the modified border will win

Note: the border will not show if auto save is enabled after 1s delay.

In today's Insider release (10-29), when enabling or disabling this setting without restarting Visual Studio, the editor will duplicate the tab when editing it.

I don't see that @Studio384, maybe it was already fixed, if not, please open an issue with details.
