MDEV-28621 group by optimization incorrectly removing subquery where subject buried in a function

A group by query optimization technique, where the a group by clause in
a subquery can be removed is incorrectly removing references to subquery
items that may be defined and used elsewhere.

This is the initial implementation of a reference counter in the unit
attached to an Item_subquery.

MDEV-33209 Stack overflow in main.json_debug_nonembedded due to incorrect debug injection

In the JSON functions, the debug injection for stack overflows is
inaccurate and may cause actual stack overflows. Let us simply
inject stack overflow errors without actually relying on the ability
of check_stack_overrun() to do so.

MDEV-33540 Avoid writes to TRX_SYS page during mariabackup operations

Fix a scenario where `mariabackup --prepare` fails with assertion
`!m_modifications || !recv_no_log_write' in `mtr_t::commit()`. This
happens if the prepare step of the backup encounters a data directory
which happens to store wsrep xid position in TRX SYS page (this is no
longer the case since 10.3.5). And since MDEV-17458,
`trx_rseg_array_init()` handles this case by copying the xid position
to rollback segments, before clearing the xid from TRX SYS page.
However, this step should be avoided when `trx_rseg_array_init()` is
invoked from mariabackup. The relevant code was surrounded by the
condition `srv_operation == SRV_OPERATION_NORMAL`. An additional check
ensures that we are not trying to copy a xid position which has
already zeroed.
