While we don't perform any sniffing yet, it does now
check all relevant mime types. Before, we would only
check specific versions of specific mime types. However,
the specification is more elaborate, which MimeClassifier
already handles.
There are two new test failures, but they actually fail
in the same way in other browsers. These tests are still
being discussed what the correct behavior should be [1]

Most tests were only being run for layout-2013, not for layout-2020.
This wasn't great since layout-2020 is now the default.
So this patch unifies the lists of included tests for both layouts.
For layout-2013 this implies adding css/css-content/, css/css-logical/
and css/css-masking/clip/.
For layout-2020 this implies adding several additional css tests, and
also tests like dom/, js/, html/, etc.
