whitespace: support multiline statusline for warnings

Add a new airline_section_warning2 that displays whitespace warnings on
a second statusline line when Vim supports the statuslineopt option
(Vim 9.2.0083+) and g:airline_multiline is set. The second line only
appears when there are actual whitespace issues, avoiding an empty
second line when the buffer is clean.
