Fix unicode newlines

Split lines in lexer only by \r\n, \r and \n

Python str.splitlines() splits by more characters[1], which, however,
causes problems when keeping these special characters in processed
templates is desirable, i.e. these bug reports: #769, #952, #1313.

The keep_trailing_newlines logic is reworked because splitlines()
removes them already (so they had to be added), while re.split doesn't
so they have to be removed.

native_concat: pass only strings to literal_eval

native_concat: pass only strings to literal_eval

If there is only single node and it is not a string, there is no point
in passing it into ``literal_eval``, just return it immediately.

One of the examples where passing a non-string node into
``literal_eval`` would actually cause problems is when the node is
``Undefined``. On Python 3.10 this would cause ``UndefinedError``
instead of just ``Undefined`` being returned.
