feat: use cosmossdk.io/log in v0.47

[julienrbrt]

Description

Use cosmossdk.io/log in v0.47 instead of CometBFT logger.
The default implementation uses zerolog, which makes the logger identical to v0.45 and v0.46 but this time with filtering fixed.

Purposely not backporting helpers like in #15358, as it will be a v0.48 improvement :)
