Abstract perform_https_request so that it can be used in Wasm context

[carlopi]

This is something I touched on recently while looking at what would it take to make possible for https://github.com/duckdb/uc_catalog to work in a Web context.

Problem is basically how to wrap a minimal API that allows to make requests either natively OR from WebAssembly (there Web and Node might be two slightly different challenges).

I think I know what's the way forward, and implementing a curl wrapper (say as a header) would allow to solve the problems in:

• duckdb/uc_catalog
• evidence-dev/duckdb_gsheets
  and possibly elsewhere.

I think it's likely on me, I can ping when I have a solution.

Given it's currently not functional, I opened a PR to disable Wasm, @archiewood, WDYT? (duckdb/community-extensions#169)

Agreed, I would love to bring this to WASM.

I'm not particularly happy with the implementation of perform_http_request() using OpenSSL as it is. It feels pretty dirty.

I was experimenting with libcurl but couldn't get it to work
