[roll third_party/pigweed] pw_sync: change SpinLock to have a constexpr ctor

Changes the pw::sync::SpinLock facade to have a constexpr
constructor. Outside of making the constructor possible to be
evaluated at compile time, this grossly simplifies the use of the
SpinLock during early boot before static global C++ constructors
are executed.
