feat(log): wire logger filtering

[julienrbrt]

Description

Closes: #15366

I have introduced log options, to make it more customizable and reduce the need of using NewCustomLogger for commonly used options.
I like the UX of variadic options: it allows us to add functionalities, without being API breaking or adding a dozen constructors. It cleaned up the logger creation in server too.

After this PR, I will be tagging cosmossdk.io/log v1.0.0.

There are a couple style details to clean up, but this otherwise looks all correct to me.
