rCOMM65b7c27c4c10: Implement interface for inter process non-blocking binary lock based on POSIX…

Summary

Implement methods from parent diff

Test Plan

Temporarily modify NotificationService and AppDelegate so that the first writes notification to a file from which the second reads upon app launch. Cover reads and writes with semaphore operations. Use debugger to hold semaphore in AppDelegate, trigger notification and see that NotificationService did not acquire semaphore (simply logs it).

15–42 ↗	(On Diff #14160)	Spacing here looks broken. Is this really how XCode is formatting it? Can we try to improve this?

native/ios/Comm/TemporalMessageStorage/NonBlockingLock.mm
15–42 ↗	(On Diff #14160)	I don't use XCode for formatting - I rely on `yarn clang-format-all` command. Spacing here looks broken. What exactly do you refer to? I think you may refer to `NSLocalizedDescriptionKey : [NSString`. Actually spacing is correct here. Additional space is introduced between `NSLocalizedDescriptionKey` and `:` since it is not a method call but initialization of Objective - C dictionary. We do no introduce before after `:` if it precedes argument in method call, but we do so if it precedes value under a given key in Objective-C dictionary initialization. Example: https://stackoverflow.com/questions/9195573/initializing-nsdictionary.
