QtBase: introduce QT_DEPRECATED_VERSION/QT_DEPRECATED_VERSION_X

Browse Source 
QT_DEPRECATED_VERSION(major, minor) and
QT_DEPRECATED_VERSION_X(major, minor, text) outputs a deprecation
warning if QT_DEPRECATED_WARNINGS_SINCE is equal or greater than the
version specified as major, minor.
This allows the user to hide deprecation warnings which can't yet be
fixed for their codebase because the minimum required Qt version does
not provide the replacement function.

If QT_DEPRECATED_WARNINGS_SINCE is not set by the user, it's set to
QT_DISABLE_DEPRECATED_BEFORE if available, otherwise to QT_VERSION.

[ChangeLog][QtCore][QtGlobal] Add new macros QT_DEPRECATED_VERSION
and QT_DEPRECATED_VERSION_X to conditionally display deprecation
warnings
