Simplify the code by not making this function pure virtual as all the
ports except MSW had to override it just to return an empty string.
Instead, just return empty string by default as it's not critical to
force the derived classes to override this function.
Unfortunately Visual Studio 2017 defaults to Windows SDK 8.1
which is not installed with it. This workaround automatically
targets the latest Windows 10 SDK when building.

This file is already included in BASE_OSX_SHARED_SRC, which is part of
wxiOS sources, so there is no need to repeat it in OSX_IPHONE_SRC as
well.
This fixes warnings about ignoring duplicate rules in the makefile
in command line builds.
The use of wxS() is an optimization which can be used to avoid an
implicit conversion from narrow to wide strings, but such optimizations
are not really needed in the samples and just make their code less
readable, so remove them.

Centralize all display-related code in wxDisplay class and avoid
duplicating or reimplementing it in wxDisplaySize() and
wxClientDisplayRect() functions.
See https://github.com/wxWidgets/wxWidgets/pull/955
Instead of forwarding to these functions from wxDisplay implementation
in wxUSE_DISPLAY==0 case, make the functions themselves wrappers around
wxDisplay, which may, or not, depending on the platform, have a simpler
implementation in wxUSE_DISPLAY==0 case, but is always available in any
case.
As part of this change, only use src/osx/core/display.cpp in macOS
builds, not iOS ones and update the Xcode project accordingly too.
This cuts down on code duplication, especially in wxGTK, and facilitates
further additions to wxDisplay API.
Move declaration of wxOwnerDrawnBase::ms_defaultMargin to correct file.
Do not include headers when wxUSE_UIACTIONSIMULATOR is disabled.
Add guards for wxUSE_DRAG_AND_DROP.
Use a different wxFont constructor in printing sample, which is also available in WXQT.
Avoid a heap allocation on every wxDisplay creation by caching the
wxDisplayImpl objects once they're created.
Currently we never invalidate the cache, but we should add a way to do
it in the future.
This speeds up wxDisplay::GetGeometry() benchmark by a factor of 4.
This benchmark shows that wxGetDisplaySize() has only minimal overhead
compared to wxDisplaySize(), but wxDisplay().GetGeometry() is almost 3
times slower (under wxGTK).
Don't check for the index validity if it's 0, which is the most common
case, as index 0 is always valid and so we can avoid calling GetCount(),
which might have a non-trivial cost, completely.
Most of the methods of wxDisplay are always available, they just only
support primary display when wxUSE_DISPLAY==0, so there is no need to
check for wxUSE_DISPLAY before using them as they already contain the
only possible fallback anyhow and such checks are useless.
This incidentally closes#18115, due to removing "#if wxUSE_DISPLAY"
around wx/display.h inclusion.
Obey the LANGUAGE environment variable (if set), which is GNU
gettext's primary way of determining language preference. Apparently
ignored by wx until now, even though wx attempts to be a
reimplementation of GNU gettext.
The LANGUAGE variable may contain a list of preferred languages,
so use that list to find the best translation.
GNU gettext has supported multiple preferred languages since forever
(at least 15 years), and therefore it is odd that this wasn't already
implemented in 01f953efb2. Instead,
it was implied that Unix does not support such. (Even if GNU is not
Unix, nothing stops a wxWidgets app supporting such nevertheless.)
