Costin Leau 61f49af497 SQL: Spec tests now use classpath discovery (#40388)
To avoid having to specify each spec by hand (which can miss specs to be
added), the test infrastructure now performs classpath discovery so that
each spec added, is automatically considered.

Relates #40358

Costin Leau 076a68007c SQL: Add multi_value_field_leniency inside FieldHitExtractor (#40113)
For cases where fields can have multi values, allow the behavior to be
customized through a dedicated configuration field.
By default this will be enabled on the drivers so that existing datasets
work instead of throwing an exception.
For regular SQL usage, the behavior is false so that the user is aware
of the underlying data.

Fix #39700

Andrei Stefan ba44f28340 SQL: ignore UNSUPPORTED fields for JDBC and ODBC modes in 'SYS COLUMNS' (#39518)
* SYS COLUMNS will skip UNSUPPORTED field types in ODBC and JDBC, as well.
NESTED and OBJECT types were already skipped in ODBC mode, now they are
skipped in JDBC mode, as well.

SQL: Allow sorting of groups by aggregates (#38042)
Introduce client-side sorting of groups based on aggregate
functions. To allow this, the Analyzer has been extended to push down
to underlying Aggregate, aggregate function and the Querier has been
extended to identify the case and consume the results in order and sort
them based on the given columns.
The underlying QueryContainer has been slightly modified to allow a view
of the underlying values being extracted as the columns used for sorting
might not be requested by the user.

The PR also adds minor tweaks, mainly related to tree output.

SQL: [Docs] Add limitation for aggregate functions on scalars (#38186)
Currently aggregate functions can operate only directly on fields.
They cannot be used on top of scalar functions as painless scripting
is currently not supported.

SQL: Implement FIRST/LAST aggregate functions (#37936)
FIRST and LAST can be used with one argument and work similarly to MIN
and MAX but they are implemented using a Top Hits aggregation and
therefore can also operate on keyword fields. When a second argument is
provided then they return the first/last value of the first arg when its
values are ordered ascending/descending (respectively) by the values of
the second argument. Currently because of the usage of a Top Hits
aggregation FIRST and LAST cannot be used in the HAVING clause of a
GROUP BY query to filter on the results of the aggregation.

Closes: #35639
