cmd/geth: more testcases for logging (#28501)

Browse Source 
* cmd/geth: more testcases for logging

This adds more edgecases around logging, particularly around handling of different types of nil-values
as concrete types and within interfaces.

Also adds tests with 'reserved' values which breaks json/logfmt formats. The json output is checked in,
but not actively used by any testcase at the moment.
