webrtcbin: fix msid line and allow customization

From https://datatracker.ietf.org/doc/html/draft-ietf-mmusic-msid-16:

> Multiple media descriptions with the same value for msid-id and
> msid-appdata are not permitted.

Our previous implementation of simply using the CNAME as the msid
identifier and the name of the transceiver as the msid appdata was
misguided and incorrect, and created issues when bundling multiple
video streams together: the ontrack event was emitted with the same
streams for the two bundled medias, at least in Firefox.

Instead, use the transceiver name as the identifier, and expose
a msid-appdata property on transceivers to allow for further
customization by the application. When the property is not set,
msid-appdata can be left empty as it is specified as optional.

nvcodec: Add new Direct3D11/CUDA mode encoder implementation

Adding new encoder elements nvd3d11{h264,h265}enc for Direct3D11
input support and re-written nvcuda{h264,h265}enc elements.
Newly writeen elements have some differences compared with old
nv{h264,h265}enc including non-backward compatible changes.

* RGBA is not a supported input format any more:
  New elements will support only YUV formats to avoid implicit conversion
  done by hardware. Ideally it should be done by upstream element
  in order to have more control on it. Moreover, RGBA support can cause
  redundant RGBA -> YUV conversion if multiple encoders are
  used for the same RGBA input
* Subsampled planar format support is dropped:
  I420 and YV12 format are not supported formats for Direct3D11.
  Although it's supported in CUDA mode, it's not a hardware friendly
  memory layout and it will waste GPU memory since UV planes
  will have large padding due to the memory layout requirement of NVENC.
* GL support is dropped: Similar to the RGBA case,
  GL support in encoder would be suboptimal if GL input is
  used by multiple encoders, because each encoder will copy GL memory
  into CUDA memory.
  Upstream cudaupload element can be used for GL <-> CUDA
  interop instead.
* No more pre-allocation of encoder input surfaces. New implementation
  will use input CUDA memory without copy (zero-copy) or
  will copy into a NVENC's input buffer struct in case of
  system memory input.

Add a function to get x/y coordinates from suitable navigation events,
and one to create a copy with given coordinate values.

For e.g. translating event coordinates, this avoids having to either
switch on the event type to select the right parse function, or
having to rely on implementation details of the underlying event
structure.

navigation: Improve interface to avoid exposing implementation details

This deprecates the current send_event interface, and the wrapper
functions based on it, replacing it with a send_event_simple interface and
wrapper function. Together with the new event constructors, this avoids
implementations having to directly access the underlying structure.

av1decoder: Sync duplicate_picture with VP9 one

Pass the current frame to the duplicate_picture callback. This makes it easier

documented that unlike VP9, it is not optional to implement this as the

default implementation.

cdoecs: av1: Copy system_frame_number in duplicate_picture

The system_frame_number is notably used by V4L2 decoder as a unique
indentifier for the frame that was decoded. This value is used to tell driver
which frame to reference, as V4L2 does not have an efficient mechanism to
otherwise pass back the frames.

For this reason, and because it is more ligical, copy the original
system_frame_number into the duplicate picture instead of using the current
frame.

rtpmanager/rtx: implement initial support for reading/writing rid extensions

Two RTP Header extensions are very relevant for rtprtxsend/receive.
1. "urn:ietf:params:rtp-hdrext:sdes:rtp-stream-id": will always be removed
2. "urn:ietf:params:rtp-hdrext:sdes:repaired-rtp-stream-id": will be written
    instead of the "rtp-stream-id" header extension.

Currently it's only a simple replacement of one header extension for
another however a future change would only add the relevant extension
based on some heuristics (like, video frames only on one of the rtp key
frame buffers, or only until the rtx ssrc has been validated by the peer)
in order to reduce the required bandwidth.

codecs: av1: Fix state when we show existing keyframe

Showing existing keyframe have special meaning in AV1. All the references
frame will be refreshed with the original keyframe information. The refresh
process (7.20) is implemented by saving data from the frame_header into the
state. To fix this special case, load all the relevant information into the
frame_header.

As there is nothing happening in between this and the loading of the key-frame
into the state, this patch also remove the separate API function, using it
internally instead.
