Implement support for wxHELP for wxMSW, wxGTK and wxOSX/Cocoa (at least when
showing the message box from the main thread, there doesn't seem to be any way
to show more than three buttons with CFUserNotificationDisplayAlert() so
"Help" button is not supported when using it).
This is useful not only on its own, i.e. to allow the user to ask for help,
but also because it brings the total number of buttons supported by the
message dialog to 4, meaning that more choices can be offered to the user
(which is rarely, but not quite never, useful).

There are no real changes in this commit but it removes all trailing white
space from our source files. This avoids problems when applying patches and
making diffs and it would be nice to prevent it from reappearing.

Use the task dialog instead of the legacy message box for wxMessageDialog
implementation under wxMSW on recent (Vista and later) Windows versions.
As part of this change, remove wxMessageDialogWithCustomLabels and integrate
its functionality in wxMessageDialogBase itself as it's now used by all
platforms.

Consistently use only "wx/foo.h" instead of "include/wx/foo.h" ("include" is
always implicit anyhow).
Also use "src/osx" instead of "src/mac" for the files in this directory.
See #12165.
