## Description
We decided to remove middlewares, and revert to antehandlers (exactly like in v045) for this release. A better middleware solution will be implemented after v046.
ref: #11955
Because this refactor is big, so I decided to cut it into two. This PR is part 1 of 2:
- part 1: Revert baseapp and middlewares to v0.45.4
- part 2: Add posthandler, tips, priority
---
Suggestion for reviewers:
This PR might still be hard to review though. I think it's easier to actually review the diff between v0.45.4 and this PR:
- `git difftool -d v0.45.4..am/revert-045-baseapp baseapp`
- most important parts to review: runTx, runMsgs
- `git difftool -d v0.45.4..am/revert-045-baseapp x/auth/ante`
- only cosmetic changes
- `git difftool -d v0.45.4..am/revert-045-baseapp simapp`
