[ruby/prism] Fix percent delimiter strings with crlfs
parse.y treats CRLF as a LF and basically "normalizes" them before parsing. That means a string like `%\nfoo\r\n` is actually treated as `%\nfoo\n` for the purposes of parsing. This happens on both the opening side of the percent string as well as on the closing side. So for example `%\r\nfoo\n` must be treated as `%\nfoo\n`. To handle this in Prism, when we start a % string, we check if it starts with `\r\n`, and then consider the terminator to actually be `\n`. Then we check if there are `\r\n` as we lex the string and treat those as `\n`, but only in the case the start was a `\n`.
