Merge rust-bitcoin/rust-bitcoin#3439: sequence: clarify sequence constant name and add FINAL 

4499b5c95b feat: rename ENABLE_RBF_NO_LOCKTIME to ENABLE_LOCKTIME_AND_RBF (ChrisCho-H)
861d97de36 feat: add FINAL constant to disable all (ChrisCho-H)

Pull request description:

  c24630e7b13312ea34f0f54ed832783ced8dde3f
  - `LOCKTIME` is used for both absolute and relative one without clear classification, which is confusing and could lead to an unexpected bug. Although it's API breaking change, current constant is so ambiguous unless understand the details of `LOCKTIME` semantic.

  9cc5dfeef178f03ea4d0786cfbaa3b8709fed644
  - Add constant `ENABLE_ALL` and `DISABLE_ALL`, which is useful for those who want to enable(disable) rbf, absolute/relative locktime.
