natural is defined as (from https://w3c.github.io/screen-orientation/#dfn-natural)
> A computer monitor are commonly naturally landscape-primary, while a mobile
> phones are commonly naturally portrait-primary.
But GeckoView sets `SCREEN_ORIENTATION_UNSPECIFIED` that is unlock orientation.
Like Blink, we should set landscape-primary or portrait-primary (depends on
current monitor).

So if orientation controller delegate isn't set, we should throw
`NotSupportedError`. But, actually, we throws `AbortError`, so this isn't
correct.
To return any DOM error from platform implementation of
`screen.orientation.lock`, I would like to change return value to
`GenericPromise`'s.

Make the ScreenOrientation part of the screen struct, as it should. Stop
using HAL to propagate just screen orientation updates, use the more
general screen manager.
Instead of HAL observers, add a simple observer service notification,
and clean a bunch of the code.
This will simplify bug 1754802 a bit, and is generally simpler.
Shouldn't change behavior. I've tested the events and some common
orientation locking use cases like Youtube, and they behave the same.

Gecko uses the redundant code from nsIScreen to SCreenConfiguration. So we
should add a convert method for newer platform implementations.

Previously, the screenOrientation.lock API was for Fennec and not supported for Fenix and multi-process use. The overall idea is to now allow apps to use the API through a delegate and make asynchronous calls to LockDeviceOrientation. This required replacing the existing code that returned a default false bool to calls that perform the requested orientation change and instead return a promise that contained either an allow or deny value.
Returning a promise instead of a bool involved changing the API calls from the C++ side to Java. The new general control flow of screenOrientation lock follows: an app calls C++ ScreenOrientation.lock() which eventually dispatches LockOrientationTask to resolve the pending orientation promise. Hal.cpp sends an IPC call to the content process and RecvLockScreenOrientation retrieves the current instance of geckoRuntime and calls the java side LockScreenOrientation. Apps must create a delegate and override onOrientationLock to set the requested orientation. In geckoview's testing, this is done with the android API setRequestedOrientation. Once a device orientation change has been triggered, native OnOrientationChange calls to NotifyScreenConfigurationChange, which notifies all observers and dispatches a change event to resolve the pending orientation promise.
Testing:
I used a demo on the GeckoView Example (https://usefulangle.com/demos/105/screen.html) to test locking to landscape orientation. This required a change to the GVE to show the app from recreating the whole thing on orientation change. In the example AndroidManifest xml file, `orientation` prevents restart when orientation changes.
The Junit/Kotlin tests were to verify that the expected orientation delegate was called with the expected new orientation value, in an orientation change, if the new orientation was the same as the current, and if the pre-lock conditions such as being fullscreen were not met.
A static preference `dom.screenorientation.allow-lock` was added to the dom group, since it affects the ui dom) and is currently turned off. C++ can access it through its mirrored variable dom_screenorientation_allow_lock (same name but with underscores). The junit tests turn the preference on and test the lock feature.

This patch removes the 'ScreenOrientationInternal' type from
dom/base/ScreenOrientation.h and moves it into the
HalScreenConfiguration.h header, renaming it simply to 'ScreenOrientation'
in the process. This has several knock-off effects:
- It allows files that needed ScreenOrientationInternal to include a much
smaller header than before
- It greatly reduces the number of headers pulled in when including Hal.h
- It clarifies the role of the type. The 'Internal' part in the name had
nothing to do with it being part of the implementation. The type was public
and called that way only to avoid clashing with the 'ScreenOrientation'
class. Since we moved it into a different namespace it can be renamed
safely.
- It allows a file that was manually re-declaring 'ScreenConfigurationInternal'
type to use the original one
- Finally this fixes a few files which were missing headers they actually
required but that would still build because unified compilation put them into
units that already had those headers thanks to ScreenConfiguration.h
