Test runner can't parse CRLF in some cases

[dfgordon]

Problem

If the test has the :error attribute and the test file uses CRLF line endings, the test will report failure incorrectly. Other attributes are also likely affected by the bug. The programmer of the tests may not figure out the line separators are the problem for some time. This appears to come from the following loop in cli/src/test.rs, maybe just tweak the closure:

for line in test_name_and_markers
    .split(|&c| c == b'\n')
    .filter(|s| !s.is_empty())
{
// ...
}

Steps to reproduce

Add :error to a unit test that has an error deliberately introduced. Change line separators to CRLF. Run tree-sitter test.

Expected behavior

Expect test runner to be able to parse either standard line separator.
