Reorganize C++ Tests

[cwharris]

I have a few changes here. Some of them might not make it depending on how others feel.

• Move test utilities in to a library to share across tests.
• Move tests in to individual executable to enforce individual tests to not sharing code.
• Use gtest_discover_tests to let ctest run and show all tests individually.
• Use gtest::gtest_main and remove explicit main entry file.
• Build and run tests by default.
• Ability to filter tests by ctest --test-dir build -R "TestCuda.*"

+ echo 'Running CTest...'

LGTM, but why are the changes to scripts/compile.sh needed?

-S . -B build is pretty standard, and it's easy to miss the . at the end.
