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!

screen: cache history offset
...
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.

This is more oriented around glyph indexes and also introduces an
important concept in the FontIndex which can be cached ahead of time so
that we can eventually break down text into runs for text shaping.
