using the base class wxHAS_NATIVE_ENABLED_MANAGEMENT in cocoa disabling/enabling child windows, fixes #16232, fixes #15495

Fix wxPoint2DInt::operator*= and wxPoint2DInt::operator/= .

These operator functions are respectively adding and subtracting their arguments. Instead let the functions multiply and divide their arguments (like their wxPoint2DDouble counterparts were doing already).

See #10946.

Cast arguments passed to wxPoint2DInt constructor.

Cast them to wxInt32 (instead of int) as that is the type of the wxPoint2DInt members m_x and m_y.

See #10946.

Add 3 missing declarations for wxPoint2DInt non-member operator functions.

Three duplicate declarations were removed in r70493 instead of replacing them with the missing declarations.

Closes #10946.

Fix bugs in wxEnumProperty introduced by r76562.

The compilation fixes introduced run-time fixes due to not account for the use
of NULL pointers (which are not accepted as choices cache but are accepted as
choices values, go figure).

Closes #16266.
