Ivan Solovev 5a5bc86028 QT_INLINE_SINCE: take version into account
This patch improves the QT_INLINE_SINCE(maj, min) macro to take
deprecation version into account.
If the specified (maj, min) version is less than or equal to the
version defined by QT_DISABLE_DEPRECATED_BEFORE, the macro will expand
to "inline", and the out-of-line fallback will be removed from the
library.

This is achieved by introducing the helper
QT_IF_DEPRECATED_SINCE(major, minor, whenTrue, whenFalse) macro.

Fixes: QTBUG-104131
Pick-to: 6.4
