Data.Maybe: add callstack for fromJust (Trac #15559)
Per feature request, add `HasCallStack` to `fromJust` in `Data.Maybe`
and use `error` instead of `errorWithoutStackTrace`. This allows
`fromJust` to print call stacks when throwing the error.
Also add a new test case for the behaviour, modify existing test cases
for new signature
Test Plan: New test cases
