Qt: Clean up the byte view hover highlight.

Rename the text highlight enum "HighlightMode" to make its use and
intent more clear. Add a mode for the offset highlight instead of using
a separate variable. Use our palette to draw the hover highlight colors.
Add a note about colors to the Developer's Guide.
