condition_variable::timed_wait incompatible with std::chrono::duration due to lack of is_pos_infinity

boost::condition_variable::timed_wait() attempts to invoke wait_duration.is_pos_infinity() on its templated parameter.

The standard doesn't define a member is_pos_infinity expected by timed_wait, forcing one to use a Boost clock rather than an STL one such as steady_clock or system_clock.

Found when compiling with MSVS 2022's STL (line 200 here):

https://github.com/microsoft/STL/blob/main/stl/inc/__msvc_chrono.hpp

A possible workaround would be to define an adapter class that defines this member.

Start at boost::condition_variable::timed_wait and inspect how its templated duration parameter is handled. Compare that expectation with the standard std::chrono::duration interface and the linked MSVS STL definition; done means standard steady_clock or system_clock durations are accepted without requiring a Boost clock.
