Original Pull Request: https://github.com/microsoft/terminal/pull/4946

State: closed
Merged: Yes

Summary of the Pull Request

Added better wide glyph support for UIA. We used to move one cell at a time, so wide glyphs would be read twice.
Converted a few things to use til::point since I'm already here.
fixed telemetry for UIA

PR Checklist

Closes Add more rules to the static analysis ruleset (#1354)

Detailed Description of the Pull Request / Additional comments

The text buffer has a concept of word boundaries, so it makes sense to have a concept of glyph boundaries too.

_start and _end in UiaTextRange are now til::point

Validation Steps Performed
