meson: Mark files as files() Making it more robust and future proof And fix issues that it creates Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1093>

Move CODEC base classes into it's own library This introduce a library which contains a set of base classes which handles the parsing and the state tracking for the purpose of decoding different CODECs. Currently H264, H265 and VP9 are supported. These bases classes are used to decode with low level decoding API like DXVA, NVDEC, VDPAU, VAAPI and V4L2 State Less decoders. The new library is named gstreamer-codecs-1.0 / libgstcodecs.

codecparsers: Reimplement VP9 parser Existing VP9 parser implementation doesn't provide information required by other stateless decoding APIs (i.e., DXVA and NVDEC), specifically loop filter and segmentation parameters might not exist current frame. So parser needs to fill the information by using previously parsed information. We can update the gstvp9parser implementation so that it can provide all information required by stateless decoding APIs with a huge API break, or adding more ugly struct in it. Instead doing as such, this commit introduce a new VP9 parser implementation. What is different from existing one? * All variables will follow the specification as much as possible: VP9 Bitstream & Decoding Process Specification - v0.6 31st March 2016 * Parser will fill all the required information for decoding frame to GstVp9FrameHeader struct. In case of old VP9 parser, user needs to read additional data from parser's member variables. * GstVp9StatefulParser object struct is completely completely opaque Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2112>
