chore: Fix flatcc linking for non-bundled case

[paleolimbot]

It looks as though nanoarrow's IPC feature was added upstream in vcpkg before I could get there; however, required a patch in the flatcc linking (and an update to flatcc, which was also done).

This PR applies the patch with some input from Opus 4.5 that will hopefully help the process (and help get the IPC feature build for homebrew as well).

Closes #796
