Running local tests fails on clean machine: framework Microsoft.VCLibs.140.00.Debug missing

### Windows Terminal version

commit 0bc66abd3b9777200178ca2f4760eaee7ab72812

### Windows build number

10.0.19044.1620

### Other Software

n/a

### Steps to reproduce

Clean install Windows; follow instructions for getting started as a contributor, build debug configuration from CMD and then do "runut" from the root of the project.

Reproduces in retail also once you fix the build breaks in the tests. ;-)

### Expected Behavior

Unit tests run clean.

### Actual Behavior

```

Start with the contributor getting-started instructions, the root-level `runut` command, and `bin\x64\Debug\TestHostApp\AppXManifest.xml`. Reproduce the clean-machine failure in a Debug build and inspect how the test host declares its framework dependencies; done means the local unit tests run without the missing `Microsoft.VCLibs.140.00.Debug` error.
