## Description
Main changes:
#### `x/auth` and `x/auth/ante` stopped depending on simapp
Some usages are left but this PR grew too much, so we might want to do it in a separate.
#### Removed all usages of the `suite` in `ante`
This makes tests way more verbose but helps keep the test cases self-contained and easier to understand (before you would need to mentally track the state of the suite throughout the test cases to understand them).
Also, it's easier to test, given that all tests are converted to standard Go unit tests (`func TestSomething(t *testing.T){`) and at least VSCode recognizes them and lets you run a single one instead of the entire suite.
I think this can/should be replicated in other modules.
Closes: #12502

## 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`

## Description
ref: #9585
This PR if the 1st step (out of 2) in the #9585 refactor. It transforms baseapp's ABCI {Check,Deliver}Tx into middleware stacks. A middleware is defined by the following interfaces:
```go
// types/tx package
type Handler interface {
CheckTx(ctx context.Context, tx sdk.Tx, req abci.RequestCheckTx) (abci.ResponseCheckTx, error)
DeliverTx(ctx context.Context, tx sdk.Tx, req abci.RequestDeliverTx) (abci.ResponseDeliverTx, error)
SimulateTx(ctx context.Context, tx sdk.Tx, req RequestSimulateTx) (ResponseSimulateTx, error)
}
type Middleware func(Handler) Handler
```
This Pr doesn't migrate antehandlers, but only baseapp's runTx and runMsgs as middlewares. It bundles antehandlers into one single middleware (for now).
More specifically, it introduces the 5 following middlewares:
| Middleware | Description |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| RunMsgsTxMiddleware | This middleware replaces the old baseapp's `runMsgs`. |
| LegacyAnteMiddleware | This middleware is temporary, it bundles all antehandlers into one middleware. It's only created for the purpose of breaking the refactor into 2 pieces. **It will be removed in Part 2**, and each antehandler will be replaced by its own middleware. |
| IndexEventsTxMiddleware | This is a simple middleware that chooses which events to index in Tendermint. Replaces `baseapp.indexEvents` (which unfortunately still exists in baseapp too, because it's used to index Begin/EndBlock events) |
| RecoveryTxMiddleware | This index recovers from panics. It replaces baseapp.runTx's panic recovery. |
| GasTxMiddleware | This replaces the [`Setup`](https://github.com/cosmos/cosmos-sdk/blob/master/x/auth/ante/setup.go) Antehandler. It sets a GasMeter on sdk.Context. Note that before, GasMeter was set on sdk.Context inside the antehandlers, and there was some mess around the fact that antehandlers had their own panic recovery system so that the GasMeter could be read by baseapp's recovery system. Now, this mess is all removed: one middleware sets GasMeter, another one handles recovery. |
