Reorganize C++ Tests (nv-morpheus#1095)

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.*"`

```
