[rd-refactoring]

Multiple refactorings and enhacements for process starting.
Removed UtSettings.logConcreteExecutionErrors and UtSettings.engineProcessLogLevel switches.
Logs for engine and concrete executor processes are always enabled.
Switched log configuration to utbot-intellij/log4j2.xml.
Use UtSettings#getIdeaProcessLogConfigFile from ~/.utbot/settings.properties to configure logs for engine and concrete executor processes without rebuilding plugin.
