[CMAKE] Unbreak the activated tests

Summary:
The tests with next upgrade activated is silently broken since there is
no longer any test suite enabled (D4698).

This diff re-enables the upgraded tests, apply them to all the boost
unit tests (and not only test_bitcoin) and run them in parallel like
any regular test.

Test Plan:

cmake -GNinja .. -DTEST_WITH_UPGRADE_ACTIVATED=ON
ninja check
