Chandler Carruth fda41783e5 Extend and adjust the terminal API for the diagnostics rendering (#7993) ...

The rendering we're trying to implement based on
`toolchain/docs/diagnostics_rendering.md` needs some features the
initial terminal API didn't support:

- Heavy stroke weight on lines
- Vertical lines that cross earlier lines without joining them
- Wrapping that keeps quoted code whole

This PR adds support for these and removes the two `buffer.h`
TODOs that described them.

This PR also tries to improve the ASCII fallback quality a bit by using
`^`-lines for "heavy" weight, and using `.` and `'` when drawing tees.
Still not perfect of course, but seems reasonable given the constraints
of ASCII rendering.
