Added highlight search setting and toggle in menu to trigger

Summary:
Created search highlight settings to be stored as part of persisted state. Added toggle/menu option in the dropdown.

This diff serves as the start of the stack that introduces highlighting the search terms in the search results of flipper. Currently, the results returned do not show why(the key word) they are appearing.

The next diffs will introduce not only the actual highlighting but also "custom"-ish color-picking for the highlights. The colors will be chosen from the sub-menu where the highlighting is enabled.
