glupload: Add VideoMetas and GLSyncMeta to the raw uploaded buffers

This is done by reusing `gst_gl_memory_setup_buffer` avoiding to
duplicate code.

Without a VideoMeta, mapping those buffers lead to GstBuffer mapping the
buffer in system memory even when specifying the GL flags (through the
buffer merging mechanism) making the result totally broken.
