Rewrite the tests! now they're cross-platform! (#7315)

* begin exploratory rewriting of tests

* continue working on tests

* more test work! holy butts vcpkg-tests/plan.cpp was a bunch of work

* finish writing new tests

  - [x] write catch2 tests
  - [ ] rewrite/at least delete the VS project files
  - [ ] document running tests

* Fix tests to work on WSL, rewrite test vcxproj

still need to test on macOS
also, delete tests.pch.h

* Condense add_test calls
