Aleksey Midenkov ddea8f6a39 MDEV-23779 Error upon querying the view, that selecting from versioned table with partitions ...

PARTITION clause in SELECT means query is non-versioned (see
WITH_PARTITION_STORAGE_ENGINE in vers_setup_conds()).

vers_setup_conds() expands such query to SYSTEM_TIME_ALL which is then
added to VIEW specification. When VIEW is queried both clauses
PARTITION and FOR SYSTEM_TIME ALL lead to ER_VERS_QUERY_IN_PARTITION
(same place WITH_PARTITION_STORAGE_ENGINE).

Fix removes FOR SYSTEM_TIME ALL from VIEW by accessing original
SYSTEM_TIME clause: the one specified in parser. As a side-effect
EXPLAIN SELECT displays SYSTEM_TIME specified in SELECT which is
user-friendly.
