Added test suite modules for level-1f, 3 kernels.

Details:
- Added test modules in test suite for level-1f kernels and level-3
  micro-kernels. (Duplication in the micro-kernels, for now, is NOT
  supported by these test modules.)
- Added section override switches to test suite's input.operations file.
- Added obj_t APIs for level-1f front-ends and their unblocked variants to
  facilitate the level-1f test modules. Also added front-end for dupl
  operation.
- Added obj_t-based check routines for level-1f operations, which are
  called from the new front-ends mentioned above.
- Added query routines for axpyf, dotxf, and dotxaxpyf that return fusing
  factors as a function of datatype, which is needed by their respective
  test modules.
- Whitespace changes to bli_kernel.h of all existing configurations.
