gh-85302: Add support for BTPROTO_SCO on FreeBSD #131981

BTPROTO_HCI addresses only expect string identifiers on NetBSD and DragonFly:

cpython/Modules/socketmodule.c

Line 1931 in 2e0a920

#if defined(__NetBSD__) || defined(__DragonFly__)

But of course this is true on FreeBSD too. (DragonFly inherited the BT stack from FreeBSD!)
For example this is how hccontrol creates an address:
https://github.com/freebsd/freebsd/blob/6bb9221a9b865ee432269099f341e4230a6cbcd4/usr.sbin/bluetooth/hccontrol/hccontrol.c#L115-L129

So currently it is not possible to bind an HCI socket (without using FFI to directly use the libc bind function) :(

BTPROTO_SCO is excluded on FreeBSD:

cpython/Modules/socketmodule.c

Line 1953 in 2e0a920

#if !defined(__FreeBSD__)

But SCO has been supported since 2008: freebsd/freebsd-src@bb4c6de

(1) was fixed by #131668.

pythongh-85302: Add support for BTPROTO_SCO on FreeBSD

gh-85302: Add support for BTPROTO_SCO on FreeBSD (GH-131981)

😍

Actually, we did not test this on live FreeBSD machine, and were unable to test it on a VM, so the support is rather theoretical. I will be grateful if someone can test it on machine where the Bluetooth socket tests are not skipped.
