cbee1d7091 depends: modernize clang flags (Cory Fields)
2a85857ce5 ci: disable false-positive warnings for now (Cory Fields)
Pull request description:
This is a cleaner and simpler alternative to #25098. Inspired by [this conversation](https://github.com/bitcoin/bitcoin/pull/27737#issuecomment-1562543301). The diff is large but the change itself is quite small.
Fixes builds with llvm >= 11 in guix by working around the problem. As a bonus, this is much cleaner and more maintainable than what we had before.
See the updated comment for more info. At a high level: rather than playing tricks and trying to work around clang's default includes, disable them and re-add what we want.

fanquake:
ACK cbee1d7091 - tested Guix and the depends cross-compile. Would like to move this along, to unblock #27676, which itself might be a blocker for #27897. Note that macOS might seem somewhat in flux for the moment, but once we finish the migration to LLVM Clang + LLD, things will be must simpler, and ultimately more maintainable.
