Merge branch 'rickard/atomic-type/OTP-8974' into dev

* rickard/atomic-type/OTP-8974:
  Use 32-bit atomics for system block
  Use 32-bit atomics for misc scheduling specific information
  Use 32-bit atomic for uaflgs in thread specific events
  Use 32-bit atomics for process lock flags
  Add 32-bit atomics to emulator APIs
  Use new atomic types in emulator
  Use 32-bit atomics for ethr_thr_create
  Use 32-bit atomics for mutex and rwmutex flags
  Use 32-bit atomics for events
  Add support for 32-bit atomics
  Move atomic API into own files
  Add support for 64-bit atomics on Windows
  Remove unused ethread time functionality
  Introduce ethr_sint_t and use it for atomics
