PEL: Refactor the test data factory

This commit has no functional changes, it just does some things
to make the PEL data creator for testcases, pelDataFactory(), be
more manageable:

- Change to return a plain vector instead of a unique_ptr<vector>.
- Keeps the data for each section in separate vectors and then
  either returns those as-is or combines them into a PEL.
- Change the TestPelType enum to TestPELType to match the style guide.
- Have pelDataFactory provide the SRC section instead of srcDataFactory.
