And also teach CMake to treat it properly instead of hardcoding the
version number.
[ChangeLog][Build System] The configure script now accepts a new
parameter -disable-deprecated-up-to which is used to remove all
deprecated code from API and ABI while building the libraries.
The version number must be specified in a hex format.
For example, it can be used like this:
/path/to/qt/configure -disable-deprecated-up-to 0x060500
to remove all code deprecated in Qt 6.5.0 or earlier releases.
