Add Profile Functionality to Fetch Phase

[andrevandeven]

Description

Extended existing profile classes to time high level fetch phase components. Operations being counted and timed:

1. Sorting the collection of document IDs before iteration.
2. Creating the stored fields visitor.
3. Building the necessary sub-phase processors.
4. Time spent getting new leaf readers.
5. Preparing hit contexts, including the time spent loading stored fields.
6. Executing each individual sub-phase.
7. The final assembly and construction of the SearchHit objects.
