Match more type stubs to the runtime

VideoStream.__getattr__ raises AttributeError for framerate and rate on
purpose, so the stub let code type-check that failed at runtime. Drop
them, along with Buffer.__bytes__ and InputContainer.flush_buffers(),
which do not exist from Python either.

HWAccel defaults allow_software_fallback to True, not False, and accepts
an int device type. ArgumentError is also a ValueError.

Add HWAccel.config, FilterContext.filter, Subtitle.type, and
VideoCodecContext.reformatter, which the runtime has and the stubs did
not.
