COMPMID-3363, COMPMID-3364: Add align_corners support to nearest neighbor

- Both NEON and CL's Scale Kernel now supports aligned corners
  with nearest neighbor interpolation
- Unsupported combination (center sampling policy with aligned
  corners) now fails on validation
- Test suites for CL and NEON are pruned by removing unsupported
  combination
