Assert and replace invariants, fasserts, MONGO_UNREACHABLE and MONGO_UNIMPLEMENTED macros usage with tassert for pointer-like structures that may reference non-owned data that's not expected to be missing.
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.
