AtlasEngine: Fix uneven baselines when scaling glyphs (microsoft#14039)

This commit changes the glyph scale algorithm to prefer aligning glyphs to
their baseline. This improves the visual appearance of simulated italic glyphs.
However wide Emojis in narrow cells now look slightly worse without centering.

Closes microsoft#13987

## Validation Steps Performed
* Use FiraCode which has no italic variant and instead uses simulated italics
* Write italic text
* Baseline is consistent ✅

vPack: fix submit branch, add github token from consvc (microsoft#13959)

Our Windows branch name changed, and I took this opportunity to resolve
an issue where vpack builds would occasionally fail due to GitHub rate
limiting the Azure DevOps IP addresses.

[1.14] Update the MUX package to 2.7.3 (microsoft#13761)

Does two things:

* the first two commits: shakes up the way we reference MUX in our projects so we can actually just
  ```xml
  <PropertyGroup Label="NuGet Dependencies">
    <TerminalMUX>true</TerminalMUX>
  </PropertyGroup>
  ```
  Like every other dependency we have
* the last commit: update to MUX.2.7.3

This is the 1.14 PR, which should be appropriately cherry-picked through to `release-1.15` and `main`
