posix-clock: introduce posix_clock_context concept
Add the necessary structure to support custom private-data per
posix-clock user.
The previous implementation of posix-clock assumed all file open
instances need access to the same clock structure on private_data.
The need for individual data structures per file open instance has been
identified when developing support for multiple timestamp event queue
users for ptp_clock.
