Adds sync::SpinLock implementation: a recursive, high-performance lock for multicore systems as an extension of low-level hw::SpinLock.

PR also:

  • Refactors low-level critical section API to hw::CriticalSection. Refactor low-level spin-lock API to hw::SpinLock.
  • Moves low-level hardware-dependent API into stk::hw namespace to clearly separate it from stk::sync implementation.
  • Adds additional tests checking ISR-unsafe kernel API.
