Before this patch we silently allowed and ignored PER PARTITION LIMIT.
While using aggregate functions in conjunction with PER PARTITION LIMIT
can make sense, we want to disable it until we can offer proper
implementation, see #9879 for discussion.
We want to match Cassandra, and for queries with aggregate functions it
behaves as follows:
- it silently ignores PER PARTITION LIMIT if GROUP BY is present, which
matches our previous implementation.
- rejects PER PARTITION LIMIT when GROUP BY is *not* present.
This patch adds rejection of the second group.

This adds to the grammar the option to SELECT a specific key in a
collection column using subscript syntax.
For example:
SELECT map['key'] FROM table
SELECT map['key1']['key2'] FROM table
The key can also be parameterized in a prepared query. For this we need
to pass the query options to result_set_builder where we process the
selectors.

Where the grammar supports IN, we add NOT IN. This includes the WHERE
clause and LWT IF clause.
Evaluation of NOT IN follows from IN.
In statement_restrictions analysis, they are different, as NOT IN
doesn't enable any clever query plan and must filter.
Some tests are added. An error message was changed ('in' changed to 'IN'),
so some tests are adjusted.

This PR removes information about outdated versions, including disclaimers and information when a given feature was added.
Now that the documentation is versioned, information about outdated versions is unnecessary (and makes the docs harder to read).

The goal is to make the available defaults safe for future use, as they
are often taken from existing config files or documentation verbatim.

The DML page is quite long (21 screenfuls on my monitor); split
it into one page per statement to make it more digestible.
The sections that are common to multiple statement are kept
in the main DML page, and references to them are added.
Closes#15053
