Significantly refactor fatal error handling
Because new glibc has changed `MINSIGSTKSZ` to be a syscall instead
of being constant, the signal posix handling needed changes, as it
used the value in constexpr context, for deciding size of an array.
It would be simple to fix it by having the handler determine the
signal handling stack size and allocate the memory every time the
handler is being installed, but that would add another allocation
and a syscall every time a test case is entered.

Instead, I split apart the idea of preparing fatal error handlers,
and engaging them, so that the memory can be allocated only once
and still be guarded by RAII.

Also turns out that Catch2's use of `MINSIGSTKSZ` was wrong, and
we should've been using `SIGSTKSZ` the whole time, which we use now.

Closes #2178

Catch2 is released!

If you've been using an earlier version of Catch, please see the Breaking Changes section of the release notes before moving to Catch2. You might also like to read this blog post for more details.

What's the Catch?

Catch2 is a multi-paradigm test framework for C++. which also supports Objective-C (and maybe C). It is primarily distributed as a single header file, although certain extensions may require additional headers.

How to use it
