Make wxMSW wxTextCtrl::AdjustSpaceLimit() safe to call in all cases.

Browse Source 
Allow calling this function not only from inside DoWriteText(): first, because
the existing code could be doing this (although this is only a concern in 3.0
branch as it was made private in the trunk) and second because it could
actually happen if the text limit was exceeded by user typing in the control.

See #15980.
