Upgrade client active object mgr tests to Catch2 (#14565)
* Upgrade client active object mgr tests to Catch2

In addition to invoking Catch2's test runner after Minetest's homemade
runner, this refactors the tests to follow the DRY principle, and gives
them expressive names and clear assertions. Catch2 is already bundled
with Minetest, so there are no added dependencies.

* Increment failed modules count for Catch2 tests

* Respect --test-module option for Catch2 tests

* Improve Catch2 --test-module behavior

This switches infostream to rawstream so that test runner output is
displayed, and returns the correct boolean depending on the results. The
tests are now found by setting the configuration instead of invoking the
command line parser.

* Test uniqueness of all IDS instead of just one

Co-Authored-By: Lars Müller <appgurulars@gmx.de>

* Include Catch2 test run in timing and logging

* Flush std::cout after printing Catch results

* Increment total tests run instead of hardcoding to 1

* Flush stderr before printing to stdout

It's necessary to flush stderr before printing to stdout in adition to
flushing stdout before printing to stderr, to make sure all output is
ordered correctly.

* Make Catch write to rawstream
