The PR removes the DomRefCell wrapper for CanvasState from `CanvasRenderingContext2D` and `OffscreenCanvasRenderingContext2D`. The reason for keeping member wrappers in CanvasState instead of overall CanvasState wrapper itself is because I believe that removing member wrappers would make it rather difficult to refactor the internal CanvasState methods in order to cover certain edge cases.
[For example](https://github.com/servo/servo/issues/23436#issuecomment-611089157): Drawing a canvas inside of itself would require getting and providing certain parameters for source canvas such as `canvas_id` and `is_origin_clean` that are currently accessed through source canvas context. Also, we might run into similar issue when creating patterns using canvas.

Fix webgl transform feedback
This allows https://www.joshmatthews.net/webxr-particles/ to run in Servo. This change corresponds with the following spec text:
```
GL_INVALID_OPERATION is generated by glBeginTransformFeedback if no binding points would be used, either because no program object is active of because the active program object has specified no varying variables to record.
```

they are doing. It also adds some clarifying comments to explain some
confusing behavior.

Dirty canvas when exiting immersive sessions
Fixes https://github.com/servo/servo/issues/26162, fixesservo/webxr#155
We basically end up in a situation where the main thread is asleep. It's unclear to me why it doesn't wake up after attempts to interact with the screen, but we stopped dirtying the canvas during the immersive session (https://github.com/servo/servo/pull/26077) so the main thread wasn't awake initially.
This is probably not the cleanest fix -- we really should not be ending up in situations where the main thread is perma-asleep -- however, we should be dirtying the canvas after exiting immersive mode _anyway_ since the contents need to be shown to the user, so this fix is still valid, even if it's not fixing the root cause.

Update checking origin trustworthy align to spec
While reading the [spec of ` Is origin potentially trustworthy? `](https://w3c.github.io/webappsec-secure-contexts/#is-origin-trustworthy), I found our second step is wrong; then, I found Josh said we didn't check it with `https` because we didn't support https in tests yet (https://github.com/servo/servo/pull/13574#discussion_r89346191).
IIRC, we've supported https wpt tests now so it might be fine to change it to align with spec.

Add 'python3-devel' to the DNF bootstrap packages list
Bootstrapping on Fedora 31 fails with a missing <Python.h> header.
That header is provided by the 'python3-devel' package.
Note that Fedora 31 does not ship Python2 packages anymore due to Python2 EOL.
Prior to this patch on Fedora 31, running `python3 ./mach bootstrap` results in the following build error:
```

After this patch, `python3 ./mach bootstrap` succeeds.

Add FromJSValConvertible for enums

This adds FromJSValConvertible implementations for webidl enums, which allows them to be used within `sequence<>`, etc.
This also uses these implementations when converting arguments.

Do not filter out platform objects when doing dictionary conversions in overload resolution
https://heycam.github.io/webidl/#es-overloads
In step 12, the platform object check is for substep 4, but importantly it only matters if `V` implements the matching interface. If not, it should be able to fall back to substep 10 and attempt conversion to a dictionary.
