Compilation fix for wxOSX/Cocoa with wxOSX_USE_NATIVE_TOOLBAR==0.

Don't use m_macToolbar when not using the native toolbar.

Do compile GetToolBarFontEncoding() which is used in any case.

Closes #15629.

No real changes, just remove an unused line from wxOSX wxListBox code.

Don't create a wxEVT_LISTBOX event unnecessarily, this is done by the helper
HandleLineEvent() function called from here.
