MDEV-13005: Fixing bugs in SEQUENCE, part 3, 1/5

Browse Source 
Task 1:
If table is added to list using option TL_OPTION_SEQUENCE (done when we
have sequence functions) then then we are dealing with sequence instead
of table. So global table list will have sequence set to true. This is
used to check and give correct error message about unknown sequence
instead of table doesn't exist.
