fix: don't double-define logger LogLevel parameters

[wdconinc]

Briefly, what does this PR introduce?

The Log_service::logger(name) call defines name:LogLevel already, so callers don't need to do this anymore. That removes the need for SpdlogExtensions.h includes in factories.

This PR removes the double defines, removes the headers, and also unifies the Acts loggers, so we don't have one for init and one for regular.

Tested with:

bin/eicrecon -Prichgeo:LogLevel=trace ../../sim_dis_18x275_minQ2\=1000_craterlake.edm4hep.root 
bin/eicrecon -Pacts:LogLevel=trace ../../sim_dis_18x275_minQ2\=1000_craterlake.edm4hep.root 
bin/eicrecon -PBEMC:EcalBarrelScFiClusters:LogLevel=trace ../../sim_dis_18x275_minQ2\=1000_craterlake.edm4hep.root 

All of which still get registered correctly and produce trace output. (Untested by this: benchmarks, tests, processors.)
