Debugger: Fix theming issues in the QML Debugger Console

Browse Source 
Use QPalette::HighlightedText for text on selected QML debugger console
items. Also, use QPalette::Highlight/Base for the background area. Both
changes make the console behave like a standard Qt itemview in that
regard, and therefore ensure a proper text contrast of selected items.

Fixes: QTCREATORBUG-25200
