Add simple implementation of content-security-policy on network requests
This needs a lot more hooks before it'll actually be a good implementation, but for a start it can help get some feedback on if this is the right way to go about it.
Part of servo/servo#4577 but we should probably track the rest of the implementation somewhere.

Synchronize WebGL layer creation with underlying GL APIs
I believe the underlying cause of #24373 is that the XR callbacks can end up executing before the XR WebGL layer setup has occurred. This was observed in the following symptom:
* a DOM exception would be thrown from inside the renderVR function, which is only called from XR's requestAnimationFrame callback
* following this, the webgl thread would panic with a GL error when executing the GL operations invoked from XRWebGLLayer::Constructor
This indicates that _somehow_ the XR rAF callback that raised an exception would have been operating on GL state that was not actually the state intended.

Always request new XR frames
Currently we only request XR frames when there is a rAF callback queued up.
This is incorrect, see https://immersive-web.github.io/webxr/#xr-animation-frame
With this change we always request updated frame state regardless of whether or not the user has queued up callbacks.
In addition to being spec-correct, this means that we can reliably listen for events in the OpenXR backend in the rAF loop itself, instead of having to set up a second spinning loop for when the rAF is inactive. This lets us implement visibility states for openxr without having to worry about the user never receiving the wakeup call because the rAF loop isn't pumping.

Issue 23607: first pass of changes for compatibility with Python3
As much as i want to migrate entirely to Python3 (see #23607), it will require some time as changes in web-platform-tests are significant and rely on upstream fixes to be merged and synced downstream.
In the meantime, lets improve compatibility with Python3 so that later, migration will be less painful.
Build system is definitely not ready yet for Python3, but its a step in the right direction.

Various XR fixes
Mostly making sure we expose the correct things on the XRSession interface.
No backend currently supports visibility state changes, and it's tricky to do this for Hololens because currently we must pump the event loop to notice these events, and only rAF pumps the event loop right now, which means that applications which choose to stop running rAF when blurred will have a problem.
