ICharAtlasRequest and ICharAtlasConfig need almost exactly the same set
of information, so it's simpler if we just merge the two types.
As an added bonus, this also adds devicePixelRatio to the config, which
helps guarantee that we won't ever accidentally end up with an atlas
using a different pixel ratio than we need.
Two parts were commented out:
- _writeStopped: This is because _xoffSentToCatchUp references this variable
and the feature is sort of half implemented/disabled.
- _clearChar: This is because some comments still reference this, it's part
of the work needed to do better line redrawing.
- Ensures that everything is only defined in one place, and everything
imports from that place.
- Moves CHAR_ATLAS_CELL_SPACING into a subdirectory of shared/ so that
CharAtlasGenerator can pull from it.
This addresses the comments on

The only thing `didCharSizeChange` was used for was to figure out if we
need to refresh the character atlas or not. However, `acquireCharAtlas`
already inspects the atlas owned by this terminal, and if it matches, it
avoids generating a new atlas.
So if `didCharSizeChange` is true and it's not needed, it quickly bails
out as a no-op. But if `didCharSizeChange` is false, and it was needed
(possible given the complexity of testing all of these edge cases), it
could introduce a bug.
I think it makes sense to just get rid of `didCharSizeChange`, and just
always call `acquireCharAtlas`.
I'm starting to pull some changes off of my large WIP branch/commit that
adds an alternative dynamic character atlas. We're going to need to
support multiple CharAtlas implementations, and this should make that
easier.
Fix issue where non-windows OS terminals don't paste newlines correctly
into misbehaving programs. As noted in JetBrains/jediterm#136, the
most practical solution is for terminals to handle this in their paste
logic. In a perfect world, all terminal programs would implement
bracketed paste mode properly, but that's a lot to ask.
- translate newlines to \r which is what terminal programs expect
