video-meta: Remove extensive validation from add_full()

Browse source 
Validation is already provided for `add_from_info()` and it's wrong for
DMA_DRM formats.

This allows adding video meta for DMA_DRM, where the video info contains
no usable information in most fields.

Additionally suggest using `add_full()` instead of the other variants
for DMA_DRM formats.

Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/-/issues/562
