Add support for WITH SESSION clause

[wendigo]

Add support for WITH SESSION clause:

WITH SESSION
    session_key = 'property',
    catalog.catalog_session_key = 'catalog_property'
SELECT 1

The syntax with both sessions and SQL functions:

WITH 
  SESSION a = 1
  FUNCTION x(a BIGINT) RETURNS BIGINT RETURN 1
SELECT x()
WITH SESSION with DML is unsupported in this PR.

Supersedes #23474

Round 4 :)

@martint I don't know how to reuse QueryAssertions here. If you can guide me, I can rewrite tests to use it. Beside that, all of the review comments were addressed so I'd like to move this forward.

@martint disregard last comment, I've managed to figure it out. I'll push it shortly.

What's the expectation if client submit multiple statements? For example:

WITH 
  SESSION s1=v1, s2=v2
  SELECT 1;
WITH
  SESSION s1=update_v1
  SELECT 2;

@chenjian2664 the WITH SESSION applies to a single query (it's query scoped):

trino> WITH SESSION time_zone_id='Europe/Warsaw' SELECT current_timezone();
    -> WITH SESSION time_zone_id='UTC' SELECT current_timezone();
     _col0
---------------
 Europe/Warsaw
(1 row)

Query 20250204_052204_00008_uu8h3, FINISHED, 1 node
Splits: 1 total, 1 done (100.00%)
0.02 [0 rows, 0B] [0 rows/s, 0B/s]

 _col0
-------
 UTC
(1 row)

Query 20250204_052204_00009_uu8h3, FINISHED, 1 node
Splits: 1 total, 1 done (100.00%)
0.02 [0 rows, 0B] [0 rows/s, 0B/s]

@sajjoseph you can find this interesting :)

[sajjoseph]

Absolutely! This will be really useful as we can embed the session variables in SQL itself. Thanks for this feature.
It will be an exciting addition as tools like Tableau doesn't allow end users to supply session parameters. Through the above PR, now end users can. Great job!

[wendigo]

@sajjoseph yes, I was thinking about these use cases :)

[martint]

I just realized this change makes the following syntax valid, even though it should fail:

trino> WITH WITH t as (SELECT 1) SELECT 1;
 _col0
-------
     1
(1 row)
