Add a `clock_gettime` emulation layer and use it to implement the `time`
entrypoint.

For windows, the monotonic clock is emulated using `QPC`.
The realtime clock is emulated using `GetSystemTimePreciseAsFileTime`.

`clock_gettime` being a header library discards the dependency chain
behind it.

This PR:

- Make `clock_gettime` a header-only library
- Add `clock_conversion` header library to allow conversion between
clocks relative to the time of call
- Add `timeout` header library to manage the absolute timeout used in
POSIX's timed locking/waiting APIs
