build: remove SHINE pool image override (to enable Server 2022) (#43287)

I am changing the default build pool image from Windows Server 2019 to
Server 2022, as the 2019 images are deprecated and their use will become
a permanent error soon.

However, I cannot do that while PowerToys contains build image
overrides. These overrides prevent it from choosing the Server 2022
images.

As a drive-by, I fixed the following issues:

- `NUGET_PACKAGES` was being read from the ambient environment. It was
used in the package cache _and_ in the WIX projects directly (!). To
make the build more predictable, we now set it during build time.
- We _still_ had build step conditions that resulted in extra work being
done during build failure.
- The release builds now produce numbered failure log artifacts just
like the CI builds do.
- I have adjusted the default disk configuration to give enough space to
`C:\`, so we no longer need the work directory override or custom data
disk.

The screenshot below is from a test run where I overrode the pool image
to be `SHINE-VS17-Latest-2022`. We do not want to do that in the final
configuration, so I had to revert that change.
