[X86] computeKnownBitsForTargetNode - add X86ISD::FANDN coverage and X86SelectionDAGTest infrastructure (#181994)
Setup X86SelectionDAGTest unit tests (matching for AArch64/ARM/RISCV pattern) to allow us to more easily test X86ISD DAG nodes.

First test is for X86ISD::FANDN nodes, which are very tricky to test in regular tests as they so often fold beforehand
