import-w3c-tests should rely on <meta name="flags"> to detect CSS manual tests

[Frédéric Wang (:fredw)]

CSS tests have additional flags, which can be used to indicate that the tests are manual:

https://web-platform-tests.org/writing-tests/css-metadata.html#requirement-flags

From WPT's tools/manifest/sourcefile.py:

def content_is_css_manual(self):
        """Boolean indicating whether the file content represents a
        CSS WG-style manual test"""
        if self.root is None:
            return None
        # return True if the intersection between the two sets is non-empty
return bool(self.css_flags & {"animated", "font", "history", "interact", "paged", "speech", "userstyle"})

Currently, import-w3c-tests just treat them as "support" files, instead of ignoring them.

s/are/or/

We should probably merge is_wpt_manualtest and is_css_manualtest

Maybe we should add asis which is a valid css flag but not classified as manual.

I never know whether the assertion message tells what is expected or what is unexpected.
I would rewrite it to 'test with CSS flag %s should be manual'

Done.

Yeah, I was also confused by existing tests. Done here and as well above "test_info should be None"
