DOMException now inherits its Javascript toString from Error
<!-- Please describe your changes on the following line: -->
stringifier is out of the DOMException IDL, and Stringifier(&self) is moved into the main body of DOMException where it can continue to be called internally.

Issue warning to devtools when module scripts in use.
This makes it easier to identify why content isn't working in environments which don't have access to the RUST_LOG output.
Various webxr WPT fixes
Needs https://github.com/servo/webxr/pull/108
r? @asajeffrey
Went through most of the failing tests and fixed them. Many of the remaining ones fail due to unsupported features that I can slowly whittle away.
Iits details are now private to the module.
It has a couple methods that take closures to make sure that "before" and "after" steps are done together:
* In an absolutely positioned box, take care of nested abspos (establish a new containing block, etc.)
* For a box that *might* be `position: relative`, optionally take care of the same.
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

Make `mach test-tidy --no-wpt` compatible with Python3
Make `mach test-tidy --no-wpt` compatible with Python3
See also #23607
After this pull request, all python files (except WPT) will be checked for Python3 syntax compatibility.

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.
