Add initial scrolling support to layout_2020
This adds very early scrolling support to layout_2020. Only the root element scrolls for now, but the idea is to continue to polish this.

Update the WebGL2 test expectations
It seems the WPT test runner/updater has some troubles picking up successful test results, so I've regenerated the `ini` files manually for the WebGL2 tests.

Return the highest priority error from the descendant instead of return the very first one
The test failed because we didn't return the highest priority error (which is network error in this case).
As Manish mentioned in https://github.com/servo/servo/issues/25436#issuecomment-571065323, that's because we're using the Promise.all trick to signal loads.
If we can avoid relying on Promise.all, maybe we don't need to do a complex logic like this; instead, ideally, we should always finish the module load immediately when we hit network failure so that we don't even need to do the `max()` comparison.

After connecting the lines of a rectangle, a new subpath has to be created containing the rectangle's origin as the only point in the subpath.

Add WebGL2 specific version strings
Updated the `VERSION` and `SHADING_LANGUAGE_VERSION` WebGL parameters to report the correct version strings when WebGL2 is in use.

Add support for WebGL2 uniform array operations
Adds support for the WebGL2 overloads of `uniform[1234][if]v`.
<!-- Please describe your changes on the following line: -->
WebGL2 adds two optional parameters for the `uniform[1234][if]v` functions to allow specifying input data ranges. However, because they have the same name and overlapping parameters, the Codegen cannot make a difference between their GL1 and 2 variants. As a workaround, I've added the new parameters to the WebGL1 side, which which isn't strictly what the spec says, but shouldn't break things either. (Note: Firefox devs also run into this issue: [[1](https://searchfox.org/mozilla-central/source/dom/webidl/WebGLRenderingContext.webidl#794), [2](https://bugzilla.mozilla.org/show_bug.cgi?id=1324543)]).

Put target element, form owner, and element document on scope chain of compiled events
Event listeners that are created from a function object just get whatever closure the function object had, but event listeners created from a string need a special closure that acts like they were defined inside a series of `with` statements. This now happens. The existing WPT test for it, html/webappapis/scripting/events/compile-event-handler-lexical-scopes.html, also relies on other behavior we don't have, so I added an easier version of the test that doesn't involve bubbling or capturing and doesn't check any IDL properties we don't have. This new test will eventually be redundant when we have everything else the upstream test expects.
