eth/filters, core/rawdb: remove unused param, refactor filtering-loop (#27891)

This change removes a chainconfig parameter passed into rawdb.ReadLogs, which is not used nor needed.
It also modifies the filter loop slightly, avoiding a labeled break and instead using a method.

This change does not modify any behaviour.
