`SoundChannel.position` was being updated by the audio manager each
tick, but the Flash Player only updates and caches the position
when `SoundChannel.position` is accessed. In contrast, an AVM1
`Sound` will constantly update its position.
This means accessing `position` only once after a sound has
finished playing will return 0.
Fixes#9952.
Despite not being MovieClips, Loader instances appear to get
the same kind of orphan handling - you can instantiate a
Loader and call 'Loader.load' without ever adding it
to a parent, and the loader will still run.
I've changed the movie code to work with a new `DisplayObjectWeak`
enum. Currently, this just supports `MovieClip` and `Loader`,
but it can easily be extended if we ever need other weak display
objects.
This also fixes a bug where we were adding the loaded MovieClip
as a child of the Loader slightly too early.
This includes the 'GetDescendants' opcode, which is used by the
the 'xml..elementName' syntax. The 'XMLList.toXMLString()
impl makes it much easier to write tests for this.
None of these formats can currently be implemented
correctly with wgpu, so we just use Rgba8Unorm instead.
The handling of opaque compressed textures is a little
sketchy - it should work for 'normal' SWFs that upload
an opaque BitmapData, but we might need to manually
adjust the alpha values if
We only support values that are neither XML nor XMLList,
since we can't yet properly stringify those.

* Bump bitflags to 2.0.0
* Sprinkle Clone, Copy, Eq, PartialEq, and Debug derives where needed
* Call `bits` on bitflags, as it is now a method
* Switch from `from_bits_truncate` to `from_bits_retain` on bitflags where needed
* Bump h263-rs for the bitflags 2.0.0 dependency
As part of porting to bitflags 2.0.0, see:
https://kodraus.github.io/rust/2022/10/07/bitflags2.html#upgrading-to-2x
We were ignoreing 'data32PerVertex'.
To make the code clearer, I've renamed the variable to
'data32_per_vertex', and made it a 'u8' (as it has a maximum of 64)
