Adds pw:🧵:Thread creation for FreeRTOS.
Note that this also refactors the pw_thread thread facade tests
to use binary semaphores and adds a helper method to re-use
test threads even if detached. Note that this is by definition
flaky without join, ergo excessive target specific sleeps are
used when needed.

Adds a std::thread like API through a new pw_thread facade based
on the STL's std::thread API, however with more restricted function
entry routine format support and backend specific option support
to permit non-portable configuration of thread settings/parameters
including static context allocations.
In addition this provides an initial set of backends based on using
the STL's std::thread directly.

Adds a std::this_thread like API through the pw_thread facades, that
is:
1) this_thread::yield
2) this_thread::sleep_{for,until}
3) this_thread::get_id
This module is split into many different facades in order to let users
decide what functionality they want to use as they may not always
be available, for example when using opaque SDKs.
In addition this provides an initial set of backends based on using
the STL's std::this_thread directly and selects them for the host
target.
