Vadim Zeitlin b270113885 Fix GetValue() returning hint for wxMSW controls with wxTE_RICH 
Override DoGetValue() in wxMSW wxTextCtrl and not GetValue() itself as
the base class version correctly takes the manually managed hints into
account, unlike the overridden version which only did this for plain
edit controls but not the rich edit ones.

Add a unit test to ensure that this bug remains fixed.

See #26176.
