Change documentation references from OS X to macOS (#1927)
Since OS X 10.12 it has been named macOS so it makes sense
to reference it in documentation as such, even when it
sometimes refers to older versions which were called (Mac) OS X.

@class wxXLocale
This class represents a locale object used by so-called xlocale API.
Unlike wxLocale it doesn't provide any non-trivial operations but simply
provides a portable wrapper for POSIX @c locale_t type.
It exists solely to be provided as an argument to various @c wxFoo_l() functions
which are the extensions of the standard locale-dependent functions (hence the
name xlocale). These functions do exactly the same thing as the corresponding
standard @c foo() except that instead of using the global program locale
they use the provided wxXLocale object.
See @ref group_funcmacro_locale for a list of wxXLocale-enabled functions.
Conversely, if a program wanted to output the number in French locale, even if
the current locale is different, it could use wxXLocale(wxLANGUAGE_FRENCH).
@section xlocale_avail Availability
This class is fully implemented only under the platforms where xlocale POSIX
API or equivalent is available. Currently the xlocale API is available under
most of the recent Unix systems (including Linux, various BSD and macOS) and
Microsoft Visual C++ standard library provides a similar API starting from
version 8 (Visual Studio 2005).
If neither POSIX API nor Microsoft proprietary equivalent are available, this
class is still available but works in degraded mode: the only supported locale
is the C one and attempts to create wxXLocale object for any other locale will
fail. You can use the preprocessor macro @c wxHAS_XLOCALE_SUPPORT to test if
full xlocale API is available or only skeleton C locale support is present.
Notice that wxXLocale is new in wxWidgets 2.9.0 and is not compiled in if
@c wxUSE_XLOCALE was set to 0 during the library compilation.
