msdk: adds util functions to handle GstContext To share GstMsdkContext with each msdk element, it will be using GstContext. Most common code is from gstreamer-vaapi. https://bugzilla.gnome.org/show_bug.cgi?id=790752

msdk: Reorganize context preparation code Split it out into a separate function with early exits to make the flow clearer, and document what the function is doing clearly. No functional changes.

MSDK: Improve the GstContext setting logic. We now can use the gst va lib's display to create our MSDK context, and use its helper functions to simplify our code. The improved logic is like this: 1. Every MSDK element should use gst_msdk_context_find() to find a MSDK context from neighbour. If valid, reuse it. 2. Use gst_msdk_ensure_new_context(). It will first query neighbours about the GstVaDisplay, if found(e.g. some VA element is connected), use gst_msdk_context_from_external_display() to create a MSDK context. 3. Then, creating the MSDK context from scratch. It creates both the display and MSDK context. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1087>
