📄 Description

This removes all glyphs from the emoji list that do not default to
"emoji presentation" (EPres). It removes all local overrides, but retains
the comments about the emoji we left out that are Microsoft-specific.

This brings us fully in line with the most popular Terminals on OS X,
except that we squash our emoji down to fit in one cell and they let
them hang over the edges and damage other characters. Oh well.

Refs #900, #5914.

Detailed Description of the Pull Request / Additional comments

Late Friday evening, I tested my emoji test file on iTerm2. In so doing, I realized
that @j4james and @leonMSFT were right the entire time in #5914: Emoji
that require U+FE0F must not be double-width by default.

I finally banged up a powershell script that parses the UCD and emits a codepoint
width table. Once checked in, this will be definitive.
