[SMS App] Add context menu to enable and disable selecting message text
Summary
PR !275 (merged) adds highlighting of message text. This interferes with the ability to scroll the messages by flicking with the touchscreen (or mouse).
This PR adds a context menu button which enables or disables selecting text in all messages.
Standard view
Or, when the window is compressed (This will become the standard view if we add more buttons to the context menu)
Test Plan
Before:
Most flicks would be interpreted as instead trying to highlight message text
After:
Highlight mode can be enabled and disabled, allowing a user to flick normally or highlight text, depending on the desired mode.
