hclsyntax: count \r\n line endings properly in source ranges

Previously we were only counting a \n as starting a new line, so input
using \r\n endings would get treated as one long line for source-range
purposes.

Now we also consider \r\n to be a newline marker, resetting the column
count to zero and incrementing the line just as we would do for a single
\n. This is made easier because the unicode definition of "grapheme
cluster" considers \r\n to be a single character, so we don't need to
do anything special in order to match it.
