Don't switch NSCell to single-line mode (wxOSX)

Browse Source 
NSCell of a single-line wxTextCtrl cannot be just switched
to the single-line mode because apart from restricting layout to a single
line this also effectively blocks processing of the Return key.

To restrict the contents of the cell to a single line we need to replace
in wxTextEntryFormatter every new line character with space (this simulates
what is done when NSCell works in native single-line mode).

Closes #18183.
Closes #18179.
Closes #18101.
See #12693.
