Changes

Remove setting of NOTARIZE_MAC_RCP in relevant jenkins files.

It seems that the setting of default value in the jenkins file take
precedence of the setting of the value in the jenkins job. Hence,
notarization has not been executed.

Implement parameter NOTARIZE_MAC_RCP the same way than other flags, for
example DEPLOY_RCP, and don't set it in the jenkinsfile. The jenkins job
configuration can take care of setting the value and provide a default
setting.

xml: Implement configuration extension for xml analysis

This patch uses the recently added extension point for configuration
source `org.eclipse.tracecompass.tmf.core.config.xmlsourcetype` for
XML analysis. The purpose of the extension point is to standardize
how configurations are managed in Trace Compass.

This commit includes JUnit tests for the XmlConfigurationSource class.
