tmf: Add configuration source extension point and classes

Introduction of "org.eclipse.tracecompass.tmf.core.config" extension
point. Extensions need to implement the interface
"ITmfConfigurationSource". The "TmfConfigurationSourceManager" will
read all extensions and interested parties can get all configuration
source types implementing"ITmfConfigurationSourceType" and their
"ITmfConfigurationSource". Using the "ITmfConfigurationSource"
instances of "ITmfConfiguration" can be instantiated and managed, e.g.
updated or removed.

This commit also contains relevant JUnit tests of the new classes.

[Added] org.eclipse.tracecompass.tmf.core.config extension point

timing.core: Refactor statistics analysis to add generic segment type

This commit refactors the existing GenericSegmentStatisticsAnalysis and
SegmentStoreStatisticsDataProviderFactory so that they can be extended
to make new statistics analysis with different grouping logic:

[1] The GenericSegmentStatisticsAnalysis is now a public class, and
provides a default implementation for the getSegmentType method. By
default, this method groups the data of a statistics analysis by segment
name. The class can be extended to overwrite the default aggregating
logic.

[2] The SegmentStoreStatisticsDataProviderFactory is split into 2
classes: The AbstractSegmentStoreStatisticsDataProviderFactory and
SegmentNameSegmentStoreStatisticsDataProviderFactory. The
AbstractSegmentStoreStatisticsDataProviderFactory provides the common
logic to generate a data provider for segment store statistics analysis.
The SegmentNameSegmentStoreStatisticsDataProviderFactory extends the
prior class, and binds the data provider to the
GenericSegmentStatisticsAnalysis, which groups the data using the
segment name. New data provider factories can extends the abstract class
to use different grouping logic for statistics analysis by binding
itself to different implementations of GenericSegmentStatisticsAnalysis.

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.

[Added] Implementation of a configuration extension for xml analysis
