When you create a `Request` object with a `FormData` body, the spec
says that the `Content-Type` header should start with
`multipart/form-data; boundary=`. However, in Servo's implementation
it started with `multipart/form-data;boundary=`, without the space.
While all reasonable servers should be able to that headers whether
the space is present or not, this brings Servo closer to the spec, and
also makes some WPT tests pass.
Note that submitting a form with `enctype="multipart/form-data"` does
produce a `Content-Type` header with the space (see
`HTMLFormElement::submit_entity_body`).

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.
