feat: add BitVec.signExtend_extractLsb_setWidth theorem (#11943)
This PR introduces the theorem
`BitVec.sshiftRight_eq_setWidth_extractLsb_signExtend` theorem, proving
`x.sshiftRight n` is equivalent to first sign-extending `x`, extracting
the appropriate least significant bits, and then setting the width back
to `w`.
