  [Support] Explicitly state that KnownBits::getMinValue/getMaxValue are UNSIGNED values. NFCI.

Update the comment to make this clear, following the same approach as APInt.

    M llvm/unittests/Support/KnownBitsTest.cpp

  Log Message:
  -----------
  [Support] Add KnownBits::getSignedMinValue/getSignedMaxValue helpers.

Add unit test coverage - a followup will update InstCombineCompares.cpp to use this and could be used by D86578 as well.
