feat: integrate fastcache

[faddat]

Description

Closes: #XXXX

This will add the -fast changes from the osmosis team to v0.45.1.

I'm going to do the same with iavl, and the like. The improvement is very much worth the changes, though it is notable that these are breaking changes and I'm not 100% sure how to handle.

(hence draft)

Also this draft PR still relies on some osmosis-versioned libraries like iavl. I have not really asked anyone but was given green light long ago "to upstream stuff" so this is just a WIP pr doing that.

thank you for making this PR. Id prefer not to break any apis and just backport the new iavl version and tm-db versions. Most of these changes shouldn't be needed.

Also the rule of thumb is merge to master than backport.
