The LCEVC_ReceiveDecoderBase() and LCEVC_ReceiveDecoderPicture() APIs from the
LCEVCdec SDK can return LCEVC_Error if the enhancement data is wrong. This
change improves the lcevcdec element to check for those errors and stop the
pipeline when that happens.

This new element wraps both the base H264 decoder and lcevcdec elements into a
bin so that LCEVC decoding works with auto-plugging elements such as decodebin.
By default, the H264 decoder element with higher rank is used as base decoder,
but any particular H264 decoder can be used by manually setting the base-decoder
property.

This new LCEVC decoder plugin is meant to implement all LCEVC decoder elements.
For now, it only implements the LCEVC enhancement decoder (lcevcdec) element.
This element essentially enhances raw video frames using the LCEVC metadata
attached to input buffers into a higher resolution frame. The element is only
meant to be used after any base decoder (eg avdec_h264).
