This avoids issues with Catch2's handler firing too early, on
structured exceptions that would be handled later. This issue
meant that the old attempts at structured exception handling
were incompatible with Windows's ASan, because it throws
continuable `C0000005` exception, which it then handles.

With the new handling, Catch2 is only notified if nothing else,
including the debugger, has handled the exception.

* Apply PR #2297 to devel branch

It turns out that Issue #2272 partially affected the devel branch. When
building tests with C++20, the compiler emits a warning that top-level
comma expressions in array subscripts are depricated. Warnings are
treated as errors, so this caused the build to fail.

This commit adds localized warning suppression
in accordance with this recommendation here:

* Fixed unknown pragma warning on old versions of gcc & clang

This commit fixes an unkwown pragma warning on older versions of GCC
and Clang. These older versions don't have a warning for depricated use
of the comma subscript. Because warning suppression is localized, and
only refers to the comma subscript warning, it doesn't affect compiler
warnings in other parts of the code.

Should fix #2116

The problem with the old name was that it collided with the
range matcher `Contains`, and it was not really possible to
disambiguate them just with argument types.

Closes #2131

This change also changes it so that test case macros using a
class name can have same name **and** tags as long as the
used class name differs.
