implement composition event creation in Document.createEvent
Solved the problem mentioned in https://github.com/servo/servo/issues/24724#issuecomment-562326328
Add logic to create composition event for Document.createEvent. This resolved some WPT test failure, so updated the metadata as well

Took out the special mouseover cancel case
<!-- Please describe your changes on the following line: -->
eventtarget.rs was checking the event type to see if it was a mouseover; now it doesn't. Other special-case events like error and beforeunload go down other code paths entirely, so this one has no special cases left.

Remove unnecessary thread in filereader, add stream TODO
<!-- Please describe your changes on the following line: -->
I think there are no benefits to queuing the various `FileReadingTask` from a thread, and reading the actual blob bytes are still done on the main-thread. We could try to move the reading off the main-thread(but note the `Blob` is not something you would want to move to another thread "as-is" since it's a `DomObject`), and I think we should just aim for implementing streams and follow the spec instead.

Workarounds for form-submission-0 tests with about:blank onloads
<!-- Please describe your changes on the following line: -->
Following the model of 3b9ab34600 these changes replace some naive onload events with equivalents that do nothing if they see an about:blank load event. Two test cases now pass, and one failing test case is now failing for a less ambiguous reason (#25154)
