Yinhang Liu bfbde5ce22 msdkdec: Enable dynamic capability support
Enable dynamic capability support for msdkav1dec, msdkh264dec,
msdkh265dec, msdkmjpegdec, msdkmpeg2dec, msdkvc1dec, msdkvp8dec,
msdkvp9dec.
The gstmsdkdec elements can create the sink caps and src caps
dynamically for different platforms.
