[DAG] Define computeConstantRange for VSCALE folding (#176027) ...

Resolves #175150 

Defines computeConstantRange and computeConstantRangeIncludingKnownBits
in the SelectionDAG. Currently only handles `ISD::VSCALE` operation
related to #174708.

Test cases were constructed to test varying VSCALE ranges on AArch64.
Further testing can be implemented as needed by review.
