Input/output tracking is intended to speed up incremental builds by
skipping a target when it doesn't need to be built. However, this seems
to be unreliable for UnitTests' AfterBuild target. Let's remove it.

It's still the case that UnitTests' AfterBuild target will be skipped if
UnitTests doesn't need to be rebuilt. (Note that UnitTests always needs
to be rebuilt if SCMRevGen changed.)

I haven't seen these problems with DolphinQt's rather similar
input/output tracking. This may be because DolphinQt's one also has the
exe file as an input/output.

Like the previous commit, but for UnitTests. This time all operating
systems were affected.

I also made UnitTests.vcxproj use the same way of copying as
DolphinQt.vcxproj, just for consistency.

This unit test compares ApprovedInis.json with the contents of the GameSettings folder to verify that every patch marked allowed for use with RetroAchievements has a hash in ApprovedInis.json. If not, that hash is reported in the test logs so that the hash may be updated more easily.
