Introduce conditional wchar_t (and std::wstring) support
The support is turned on by default but the user might need to be able to turn it off which is now possible by defining CATCH_CONFIG_NO_WCHAR.

`CATCH_CONFIG_WINDOWS_CRTDBG` is off by default. If enabled, Windows's CRT is used to check for memory leaks, and displays them after the tests finish running.

`CATCH_CONFIG_WCHAR` is on by default, but can be disabled. Currently

it is only used in support for DJGPP cross-compiler.

These toggles can be disabled by using `_NO_` form of the toggle, e.g. `CATCH_CONFIG_NO_WINDOWS_SEH`.
