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. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4177>
