[ValueTracking] Improve KnownBits for signed min-max clamping (#120576 )

A signed min-max clamp is the sequence of smin and smax intrinsics,
which constrain a signed value into the range: smin <= value <= smax.
The patch improves the calculation of KnownBits for a value subjected to
the signed clamping.
