Remove per thread instances of Endgames. (#2056)

Browse Source 
Similar to PSQT we only need one instance of the Endgames resource. The current per thread copies are identical and read only(after initialization) so from a design point of view it doesn't make sense to have them.

Tested for no slowdown.
