Move header from internal

[oboukli]

Move catch_test_run_info.hpp from directory src/catch2/internal/ to be directly under src/catch2/.

Header catch_test_run_info.hpp defines Catch::TestRunInfo which is part of the public API, since it is required when overriding Catch::EventListenerBase.

Fixes issue caught by Clang Tidy misc-include-cleaner check.

I spent some time thinking about this.

The change is of course technically correct. However, the change also has a good chance of breaking someone's build, while not having a large payoff. I've ended up deciding to merge the PR, because it won't break most users and the fix is easy.
