Assert and replace invariants, fasserts, MONGO_UNREACHABLE and MONGO_UNIMPLEMENTED macros usage with tassert for enums that are used to represent the state of an internal FSM or a member of an object, who's lifetime is bounded by the duration of a single operation and is not visible to other operations.
This ticket is only concerned with the query owned code located in src/mongo/db/exec/sbe.

Assess the invariants against this checklist:

• Invariant is not on the write path.
• Invariant is not asserting data coming from the storage layer.
• Invariant is not asserting the shared state that's accessible from other threads.
• Tassert would release all the resources that are violating the invariant.
• Invariant is covered by either unit test of jstest.
