New Screen Storage
...
This rewrites the "screen" implementation. The immediate user-impacting highlights:
* `time cat <large file>.txt` is ~25% faster
* Fully loaded (full scrollback) memory usage is 25% smaller
* Scrollback is now dynamically allocated. This lowers initial memory usage
* Resize without reflow (common with full screen apps like vim) is now ~10% faster
* Resize with text reflow is ~20% faster when the column count doesn't change
* All resize operations now maintain the cursor position correctly in more cases
Besides those impacts, the goals of this rewrite was to lay the foundation for the screen state to performantly handle text shaping (ligatures) and grapheme clusters (unicode zero-width joiners, combination markers, etc.). This new structure will let us track dirty state on a row-by-row basis for better caching of GPU resources, eventually (not in this PR), which is particularly important for text shaping (ligatures).

use an arena allocator for tty allocs
...
libuv always called the alloc cb right before read, and read owns the
buffer. By using an arena, we're probably just reusing the same buffer
over and over again. This should be quite fast.
In tracing, this indeed changes the MTPC on ttyReadAlloc from ~750ns to
~275ns. I'll take it!

This is a super hot calculation so taking up memory to cache it resulted
in 15m less function calls when catting a 10mb file, and ~5% speedup.
