Document why is safe ttValue == VALUE_NONE We can have ttValue == VALUE_NONE when we use a TT slot to just save a position static evaluation, but in this case we also save DEPTH_NONE so to avoid using the ttValue in search. This happens to work, but due to a number of lucky and tricky cases that we now documnet through a bunch of asserts and a little change to value_from_tt() that has no real effect but clarifing the code. No functional change.
