Arrow buffer Size Option

[pdet]

This PR allows users to set the Arrow Buffer Size used for Strings, BLOBS, UUIDS.

It can be set by changing the arrow_large_buffer_size option.

SET arrow_large_buffer_size=True

By default, it also changes DuckDB to output regular buffer sizes.

Obs: Currently, the extension building CI is failing. The Arrow-IPC extension PR duckdb/arrow#12 should be merged first, and the extension retagged to fix all the extension CI.

OBS2: I consider this somewhat of a bug fix, but I can retag it to feature if desired.

Looks good to me, could maybe use a couple extra tests since this changes a lot of different places where arrow is produced.

Of the top of my head, a scalar UDF test that makes sure the strings passed to the UDF are of the correct type could be nice

Hi @pdet!
I guess WebAssembly CI will fail, given that the is an incompatibility (chicken & egg, ...), I will do the (minor) changes WebAssembly side, I'd say this looks stable, and then we merge the two PRs them more or less together (so subsequent CI will not fail).

Thanks!
