This patch changes the output type of `EncoderConfigToDecoderConfig`
from `{Audio, Video}DecoderConfigInternal` to `{Audio,
Video}DecoderConfig`, moving the output from the return type to an
output parameter. This refactor serves two purposes:
1. Simplified decoder config generation: It streamlines the generation
of a decoder config from the encoder config and encoded data,
removing the need for a temporary `*DecoderConfigInternal`
intermediary.
2. More flexible dtor visibility: It eliminates the need for a public
`*DecoderConfigInternal` dtor, as it's no longer the return type.
This is crucial for the upcoming patch, which will store the
`*DecoderConfigInternal` within a `RefPtr`, necessitating a private
dtor for the inner data type.
