GETRF: Integrate IPIV array in the interface and testings

• Fix some issues in the actual getrf testing:

  • seed incorrectly initialized
  • Diagonal not dominant by default => Since LU NoPiv, diagonal dominant is the default for the generation.
  • Integrate the swap locally on the home node 0 if needed.

• Add the IPIV to all getrf interfaces

This is part of the MR !378 (merged) and is a follow-up of !392 (merged)
