Chandler Carruth c608c35e12 Rework the initial terminal rendering into the form the design landed on (#7994) 
There were a number of iterations on the design that weren't reflected
in the initial port to the terminal rendering library. This PR tries to
complete the rendering side of things to match the design we landed on:
code-focused, with messages attached by lines to the code, and condensed
as much as possible to avoid the vertical space.

It also improves the styling to make things more visually
distinguishable such as adding a `->` to the main error line, and making
the underlines and connectors for it have a heavy weight (when the font
supports that).

Another major change is having multiple messages on a single line be
drawn in source lexical order. This requires the connectors to cross
without joining, but makes it easier to read the messages.

This PR also has some refactorings to enable these improvements, and a
_number_ of improvements to comment prose and terminology to try and
avoid jargon and make things read more naturally. Sorry for the fact
that Claude left a bunch of this mannerly language in comments despite
my efforts, but I'm continuing to try and drive the prose towards
something direct and simple to read. Some of the terminology
improvements also needed to be made in the design doc and those have
been made here.

Note that I don't think this rendering is perfect or should be viewed as
final. I'm happy to iterate on it further, and have a few adjustments in
mind already, but would like to focus this on getting the
_implementation_ of the current rendering design in place, and then we
can make targeted changes or tweaks as needed. For example, I'm not yet
fully happy with the rendering when messages are too long and we move
them all the way to the left, but am leaving that for a follow-up.
