[PFW] Take into account base offset when accessing value of parameters

BZ: 88357

This patch aims to offer the possibility of accessing the value of
parameters from a Configuration blackboard instead of Main blackboard.
The read/write operation is now relative to the base offset of the
ancestor element associated to the Configuration.
The base offset is stored in the ParameterAccessContext.
