MDEV-28958 Crash when checking whether condition can be pushed into view
Do not set any flags in the items for constant subformulas TRUE/FALSE when
checking pushability of a formula into a view. Occurrences of these
subformulas can be ignored when checking pushability of the formula.
At the same time the items used for these constants became immutable
starting from version 10.7.

message:
MDEV-30706 Different results of selects from view and CTE with same definition
MDEV-30668 Set function aggregated in outer select used in view definition
This patch fixes two bugs concerning views whose specifications contain
subqueries with set functions aggregated in outer selects.
Due to the first bug those such views that have implicit grouping were
considered as mergeable. This led to wrong result sets for selects from
these views.
Due to the second bug the aggregation select was determined incorrectly and
this led to bogus error messages.
The patch added several test cases for these two bugs and for four other
duplicate bugs.
The patch also enables view-protocol for many other test cases.
