Use wxTE_RICH2 for in-place wxGrid text editor control.

This works around a bug with the plain text edit control under MSW which seems
to totally lose its caret when we hide it and show it again for another cell.

This is not a proper fix for the problem, of course, but at least it does
allow to edit wxGrid cells in the meanwhile.

Closes #11681.
