PCLF: Separate SFU functionality configuration into a new struct
Creates the EmulatedSFUConfig that will receive the parameters for
controlling the virtual SFU used in the call.
Its current only field is the previous target_spatial_index from
VideoSimulcastConfig.
This allow to filter out the bottom layers for SVC S mode tests
and enable them.
