Subject: [PATCH] MDEV-39433: Crash when recording context for a sequence query

With optimizer_record_context enabled, a simple query involving sequence
such as:

create sequence s1;
Explain select * from s1;

is crashing in store_optimizer_costs(). There are no costs associated
with sequence tables, and their fields, and hence when trying to access
cost information for them, a crash occurs.

Solution
========
Don't try to store stats or cost information for sequences
