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_DISABLE_STRINGIFICATION // Disable stringifying the original expression
CATCH_CONFIG_DISABLE // Disables assertions and test case registration
CATCH_CONFIG_WCHAR // Enables use of wchart_t
Currently Catch enables `CATCH_CONFIG_WINDOWS_SEH` only when compiled with MSVC, because some versions of MinGW do not have the necessary Win32 API support.

`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`.
