  1. storage/engine: invalidate cached iterator state when necessary 

    `Iterator.{MVCCGet,MVCCScan,FindSplitKey,ComputeStats}` need to
invalidate the cached iterator state. They were previously failing to do
so which could lead to rare scenarios where a key could be considered
present in the database which had never been written.

Fixes cockroachdb#28025

Release note (bug fix): Fix rare scenario where the value written for
one system key was seen when another system key was read leading to the
violation of internal invariants.
