Original Pull Request: https://github.com/microsoft/terminal/pull/13025

State: closed
Merged: Yes

Previously this project used a great variety of types to present text buffer
coordinates: short, unsigned short, int, unsigned int, size_t,
ptrdiff_t, COORD/SMALL_RECT (aka short), and more.
This massive commit migrates almost all use of those types over to the
centralized types til::point/size/rect/inclusive_rect and their
underlying type til::CoordType (aka int32_t).

Due to the size of the changeset and statistics I expect it to contain bugs.
The biggest risk I see is that some code potentially, maybe implicitly, expected
arithmetic to be mod 2^16 and that this code now allows it to be mod 2^32.
Any narrowing into short later on would then throw exceptions.

PR Checklist

Validation Steps Performed

Casual usage of OpenConsole and Windows Terminal. ✅
