releng: Replace org.apache.log4j with org.slf4j.binding.simple
SWTBot project has removed org.apache.log4j from their update site since version 4.0.0 in 2022-06 with Bug 578065. It is instead using org.slf4j. Trace Compass has been using fixed SWTBot version 3.1.0 since then. It will now use the latest SWTBot release and use slf4j api for logging, with the simplelogger binding.
Update all targets to use latest SWTBot repository.
Update all targets to add org.slf4j.binding.simple from Orbit.
Update all *.swtbot.tests plug-ins to remove dependency on org.apache.log4j and add dependency on org.slf4j as an Import-Package.
Remove log4j logger configuration from all SWTBot tests.
Update pom.xml to add org.slf4j.binding.simple as extraRequirement for SWTBot test plug-ins. This enables the binding in CI.
Create org.eclipse.tracecompass.slf4j.binding.simple.properties fragment plug-in to org.slf4j.api fragment host to include simplelogger.properties file that configures simplelogger to use System.out as logFile and debug as defaultLogLevel.
[Changed] Replace org.apache.log4j with org.slf4j.binding.simple
