Previously, each warning suppression was self-contained, with its own pair of `SUPPRESS_X_WARNING` and `UNSUPPRESS_X_WARNING` macros. This had the obvious advantage of being self-containing, but it also meant that if we needed to suppress more than one warning in a single place, then we would manipulate the compiler's warning state multiple times, even though logically we would only need one layer. The new way of suppressing warnings in macros is to push compiler's warning state with `CATCH_INTERNAL_START_WARNINGS_SUPPRESSION` macro, then disable whatever macros we need with the `CATCH_INTERNAL_SUPPRESS_X_WARNINGS` macro, and then return to the previous state using `CATCH_INTERNAL_STOP_WARNINGS_SUPPRESSION`.
