* 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:

When a MovieClip is an 'orphan' (it has no parent),
it still has frames run (including frame scripts). Some SWFS
like SteamBirds and 'This is the Only Level TOO' rely on this behavior,
so we need to implement it.
The overall idea is straightforward - we keep a global list of
orphan movies, which we add to whenever we unset the parent for a movie.
This list stores weak references for consistency with Flash.
When we run a frame, we process entries in the root movie list,
in addition to the normal recursive processing from the `Stage`.
However, exactly matching Flash's output turned out to be quite tricky.
The particular sequence of calls I make in `run_all_phases_avm2` makes Ruffle
pass two complicated test cases, but there could still be lurking bugs.
This is enough to get SteamBirds to the first level (which doesn't
render due to a different error).
This is a very large diff, but most of it comes from test files and
output.
This PR ads partial support for the following Stage3D shader features:
* Normal (square), rectangle, and cube textures
* Varying and temporary registers
* Lots of opcodes
The combination of these allows us to get a raytracing program
fully working in Ruffle. I've included it as image test.
Currently, this test is very slow (about 90 seconds on my machine),
as the code I'm using (https://github.com/saharan/OGSL) includes
its own shader language and compiler. THe raytracing demo
first compiles its own shader language to AGAL, and then starts
rendering the scene.
Limitations:
* Many opcodes are still unimplemented
* Most non-default texture options (e.g. mipmaps) are not implemented
`build_output_stream` now takes in a `timeout` parameter - I've
passed in `None` to keep the current behavior.
cpal addded lots of new `SampleFormat` enum values. For now, I'm
just returning an error if we encounter any of them - a quick test
showed that desktop audio is still working on my Linux machine.
