logging: remove global logger

[fasmat]

Description

After #4749 there are still some parts in go-spacemesh left that use the global logger instead of a service-specific one. This makes testing & configuration of those logs more difficult.

Affected code

Specifically the following packages still use the global logger in some places:

• events
• common/types
• hare
• events in grpcserver

Todo:

• Don't use a global logger in the poet client #4783
• remove uses of global logger in package events
• remove global logger completely

The logger in those packages is used in functions that are not part of a service and thereby do not yet have a logger thats injected into them. Consider removing them by one of the following:

• adding the functions as methods to an existing or new service
• returning an error and have the caller log the event
• drop the log (in case it is already logged upstream)
