ra: assert when using params with dimensions

This came up in #9828. According to the header comments, creating a 1D
ra_tex requires height and depth to be set to 1. For a 2D texture, it
requires depth be set to 1. There were a couple of spots in mpv's code
where this wasn't being followed. Although there was no known bug from
this, the rest of the code works like this so it was a good idea to go
ahead and sync it up. As a followup, let's just add some simple asserts
to ra.c to enforce this so it doesn't go unnoticed in the future.
