Wildcards are not allowed in toplevel ItemGroups in vcxproj; they must
be generated by targets.
We mostly use wildcards for pulling in PRI files that are dumped on disk
by the translation tool. We don't want to check those in, so we can't
expand references to them.
To that end, I've introduced a new target that will take a list of
folders containing resw files and expand wildcards under them.
All[1] other wildcards have been moved into their respective targets
_or_ simply expanded.
[1]: Nothing has complained about the resource wildcards in
CascadiaResources.build.items, so I haven't exploded it yet.
Fixes#6214.
This brings support for "Compact" tab sizing, which compresses all inactive tabs to just the size of their icons plus the close button. Neat!
It also just keeps us generally up-to-date and good citizens.
## Summary of the Pull Request
New year, new unittests.
This PR introduces a new project, `TestHostApp`. This project is largely taken from the TAEF samples, and allows us to easily construct a helper executable and `resources.pri` for running TerminalApp unittests.

## Detailed Description of the Pull Request / Additional comments
Unittesting for the TerminalApp project has been a horrifying process to try getting everything pieced together just right. Dependencies need to get added to manifests, binplaced correctly, and XAML resources need to get compiled together as well. In addition, using a MUX `Application` (as opposed to the Windows.UI.Xaml `Application`) has led to additional problems.
This was always a horrifying house of cards for us. Turns out, the reason this was so horrible is that the test infrastructure for doing what we're doing _literally didn't exist_ when I started doing all that work last year.
So, with help from the TAEF team, I was able to get rid of our entire house of cards, and use a much simpler project to build and run the tests.
Unfortunately, the latest TAEF release has a minor bug in it's build rules, and only publishes the x86 version of a dll we need from them. But, the rest of this PR works for x86, and I'll bump this when that updated version is available. We should be able to review this even in the state it's in.
