Unfortunately, I think you'll have to compile a list of this information yourself. That list you mentioned is a great place to start. The problem is that there are so many manufacturers and so many different models, I don't know that anyone has bothered to catalog all of them with all of their particular specs in one easy-to-read place.
Finding the maximum HTML5 DB size for each device will probably be the most difficult thing. If you're looking for an upper bound on space usage, just go with the lowest you find.
If you do end up finding or compiling this list, be sure to post it here... there's a lot of Android devs who would be interested in seeing it.
