exec: implement window functions in vectorized engine

[yuzefovich]

• exec: add Partitioner operator to handle PARTITION BY clause of window functions #37034 add sorting partitioner
• exec: support all window functions in vectorized engine #37035 support all window functions (i.e. not aggregates)
• exec: support all aggregates as window functions in vectorized engine #37036 support all aggregates as window functions
• exec: support window frames for window functions in vectorized engine #37037 support window frames
• exec: add optimized versions of aggregates/window functions for certain window frames #37039 add optimized versions of aggregates/window functions in some cases
• colexecwindow: add hashing window partitioner #37228 add hashing partitioner

Should we just close this in favor of #37228 since that's the only remaining task?

[yuzefovich]

Yeah, I think it's ok to close this. We're still missing the support of some aggregate functions used as window functions (required for full parity with the row-by-row engine) - those that are supported via the "default agg fn" in the vectorized engine as well as the support for FILTER clause. I'll open up separate issues for those. #37228 is an optimization that will allow the vectorized engine to not sort the input data set when ORDER BY clause is omitted by PARTITION BY clause is present.
