Commit attr runs less frequently by accumulating length of color run (#6919 )

The act of calling `InsertAttrRuns` is relatively slow. Instead of
calling it a bunch of times to meddle with colors one cell at a time,
we'll accumulate a length of color and call it to make it act all at
once. This is great for when one color full line is getting replaced
with another color full line OR when a line is being replaced with the
same color all at once. There's significantly fewer checks to be made
inside `InsertAttrRuns` if we can help it out by accumulating the length
of each color before asking it to stitch it into the storage.

Validation
----------

- Run `time cat big.txt` and `time cat ls.txt` under VS Performance
  Profiler.
