Bastin 6a9bcbab3a logging: per package verbosity (#16272) ...

**What type of PR is this?**
Feature

**What does this PR do? Why is it needed?**
This PR adds a `--log.vmodule` flag to the beacon-chain and validator
apps, that allows setting a different verbosity for every* package.

*: not every package, but most packages. (all packages that define their
logger variable with a `package` field)

Combined with the `--verbosity` flag this allows users to control
exactly what they see.

This affects both the terminal and the log file (`--log-file`), but not
the ephemeral debug log file.

example usage: 
```
./beacon-chain --log.vmodule=beacon-chain/p2p=info,beacon-chain/sync=error,beacon-chain/sync/initial-sync=debug
```

There are improvements to be done later, like accepting just the package
name instead of the full path, etc.
