til::point (#4897)
## Summary of the Pull Request
Introduces convenience type `til::point` which automatically implements our best practices for point-related types and provides automatic conversions in/out of the relevant types.

## PR Checklist
* [x] In support of Differential Rendering #778
* [X] I work here.
* [x] Tests added/passed
* [x] I'm a core contributor.

## Detailed Description of the Pull Request / Additional comments
- Automatically converts in from anything with a X/Y (console `COORD`) or x/y (Win32 `POINT`)
- Automatically converts out to `COORD`, `POINT`, or `D2D1_POINT_2F`.
- Constructs from bare integers written into source file
- Default constructs to empty
- Uses Chromium Math for all basic math operations (+, -, *, /)
- Provides equality tests
- Accessors for x/y
- Type converting accessors (that use safe conversions and throw) for x/y
- TAEF/WEX Output and Comparators so they will print very nicely with `VERIFY` and `Log` macros in our testing suite.
- A natvis

## Validation Steps Performed
- See automated tests of functionality.
