This has two effects:
1) This significantly improves the performance of ApprovalTests
run in WSL, because running the massively multi-reporter
test would cause lots of small and parallel writes across the
WSL-Windows FS boundary, completely mudering performance.
2) ApprovalTests can be run from multiple build dirs in parallel,
as long as they do not fail. However, if they do fail,
the multiple runs will still step on each other toes when
writing the unapproved files for user.
This is primarily done to support new `std::*_ordering` types,
but the refactoring also supports any other type with this
property.
The compilation overhead is surprisingly low. Testing it with
clang on a Linux machine, compiling our SelfTest project takes
only 2-3% longer with these changes than it takes otherwise.
Closes#2555
They also got slapped with the `[approvals]` tag in the process,
because we have too many approval tests and want less of them,
and these particular tests don't bring much value.

This changes the compact reporter's summary of test run totals to use
the same format as the console reporter. This means that while output is
no longer on a single line (two instead), it now includes totals for
`failedButOk` test cases and assertions, which were previously missing.
There is an increasing number of places where Catch2 wants to parse
strings into numbers, but being stuck in C++14 world, we do not
have good stdlib facilities to do this (`strtoul` and `stoul`
are both bad).
* meson: run through muon's fmt to fix formatting
* meson: switch arrays to files
Allows muon to alphabetically sort files. switch headers back to arrays
as split() can only be used on strings.

The Meson[1] build system makes it easier incorporate third-party
libaries into a project if they also build using Meson.
Let's add a minimal Meson build that's compatible with the CMake build,
along with a GitHub workflow to check that it builds and that at least
the simplest SelfTest runs.
The handling of catch_user_config.hpp is inspired by BUILD.bazel and
doesn't attempt to support any configuratons options. Such features
could be added later.
Meson strongly discourages using wildcards to specify sources, so the
source and header lists are copied from CMakeLists.txt.
Add a new test workflow to test the Meson builds. I was unable to get
these tests to pass with Ubuntu 20.04, so they use Ubuntu 22.04.
I'm neither a CMake nor a Meson expert, but the results seem to work for
me.

MinGW doesn't support `__try` and friends at all, while Clang
only supports it partially, and the test would require some
changes to make it work there. Since this is only a test, we can
afford to keep it MSVC-only.
Closes#2447
This might become potentially useful in the future, when we want
to provide the ability to forward jump generators, to be able to
simply reproduce specific input to a test.
I am not yet sure how it would work, but the basic idea is that
it could be similar to the `-c` switch for selecting specific
`SECTION` in a test case.
This is kinda messy, because there is no good way to signal to
the compiler that some code uses direct comparison of floating
point numbers intentionally, so instead we have to use diagnostic
pragmas.
We also have to over-suppress the test files, because Clang (and
possibly GCC) still issue warnings from template instantiation
even if the instantion site is under warning suppression, so the
template definition has to be under warning suppression as well.
Closes#2406
