Related to issue #1047
After this it should be possible to build a working `packager` application from the `cmake` branch. Some further logging improvements may be needed to get full parity with the `main` branch in terms of ability to do verbose debug logging, but other than that everything is expected to work.
The keys can be specified in --keys option, with the form of
label=<label>:key_id=<32-digit hex string>:key=<32-digit hex string>,label=...
There can be multiple "label=..." block. The DRM label can be one
of "AUDIO, SD, HD, UHD1, UHD2" or a custom label.
Mark --key and --key_id as deprecated. We can achieve the same result
with --keys=label=:key_id=<key_id>:key=<key>.
Also add a new optional field in stream descriptor: drm_label, which
is used to overwrite the internally generated DRM label for the stream.
If not provided, the DRM label is generated automatically based on
audio/video information, e.g. resolution.
Code changes:
- Merged RawKeyEncryptionParams and RawKeyDecryptionParams into
RawKeyParams.
- Make FixedKeySource accepts RawKeyParams as input.
