roll: pigweed pw_allocator: Add MeasureFragmentation

This CL provides an implementation of the algorithm to calculate a
fragmentation metric that was only previously described. This typically
shouldn't be invoked on device unless there is robust floating point
support. Adding this method allows platforms that do have floating
support to avoid implementing it themselves, as well as providing it for
host tasks like benchmarking.
