Put wxDECLARE_EVENT_TABLE at the end of wxTextCtrl declaration

This fixes the access specifier effectively used for the members
following these macros, as it's changed to "public" inside them, meaning
that e.g. m_privateContextMenu was actually public even though it was
ostensibly declared in the private section and the intention was for it
to be private.

Closes #16038.
