[libpas] Use futex-based locking in Windows / FreeBSD
https://bugs.webkit.org/show_bug.cgi?id=306203
rdar://168860161
Reviewed by Justin Michaud and Sosuke Suzuki.
This patch adds futex locking in Windows / FreeBSD as well.
Also remove spinlock, as all libpas-suppoting platforms support
this new locking. Also move slow path code to C side to avoid bloating
code for locking.
