Add support for autodetecting URLs and making hyperlinks (#7691)

This pull request is the initial implementation of hyperlink auto
detection

Overall design:
- Upon startup, TerminalCore gives the TextBuffer some patterns it
  should know about
- Whenever something in the viewport changes (i.e. text
  output/scrolling), TerminalControl tells TerminalCore (through a
  throttled function for performance) to retrieve the visible pattern
  locations from the TextBuffer
- When the renderer encounters a region that is associated with a
  pattern, it paints that region differently 

References #5001
Closes #574
