audio/openal-soft: Update to 1.23.1

Add PIPEWIRE and SIMD options.

Add checks to disable CPU instruction sets that are opt-out by default
and only consider the host builder. For example, disable SSE4.1 on an
amd64 host building for an i386 target. Additional instruction sets can
be enabled by setting CPUTYPE appropriately in /etc/make.conf or in its
poudriere(8) counterpart.
