Place as much as possible of the TT implementation in tt.cpp, rather than in the header. Some commentary is added to better document the public interface. Fix the search read-TT races, or at least contain them to within TT methods only.

Fix a very theoretically possible heap corruption if GetActiveProcessorGroupCount changes between calls. 3. Fully determine affinity on Windows 11 and Windows Server 2022. It should only ever be indeterminate in case of an error. 4. Separate isDeterminate for old and new API, as they are &'d together we still can end up with a subset of processors even if one API is indeterminate. 5. likely_used_old_api() that is based on actual affinity that's been detected 6. IMPORTANT: Gather affinities at startup, so that we only later use the affinites set at startup. Not only does this prevent us from our own calls interfering with detection but it also means subsequent setoption NumaPolicy calls should behave as expected. 7. Fix ERROR_INSUFFICIENT_BUFFER from GetThreadSelectedCpuSetMasks being treated like an error.
