Subject: [PATCH] Add more details to --list-encoders output

Add more information about each codec (hw/sw, vendor, alias).

Before:

    [server] INFO: List of video encoders:
        --video-codec=h264 --video-encoder=c2.exynos.h264.encoder
        --video-codec=h264 --video-encoder=c2.android.avc.encoder
        --video-codec=h264 --video-encoder=OMX.google.h264.encoder
        --video-codec=h265 --video-encoder=c2.exynos.hevc.encoder
        --video-codec=h265 --video-encoder=c2.android.hevc.encoder
        --video-codec=av1 --video-encoder=c2.google.av1.encoder
        --video-codec=av1 --video-encoder=c2.android.av1.encoder
    // audio encoders omitted

After:

    [server] INFO: List of video encoders:
        --video-codec=h264 --video-encoder=c2.exynos.h264.encoder         (hw) [vendor]
        --video-codec=h264 --video-encoder=c2.android.avc.encoder         (sw)
        --video-codec=h264 --video-encoder=OMX.google.h264.encoder        (sw) (alias for c2.android.avc.encoder)
        --video-codec=h265 --video-encoder=c2.exynos.hevc.encoder         (hw) [vendor]
        --video-codec=h265 --video-encoder=c2.android.hevc.encoder        (sw)
        --video-codec=av1 --video-encoder=c2.google.av1.encoder           (hw) [vendor]
        --video-codec=av1 --video-encoder=c2.android.av1.encoder          (sw)
    // audio encoders omitted
