Summary [libpas] De-singletonize pas_large_map to allow for multiple instances

rdar://174512866 Currently, libpas uses singletons for the various large-map hashtables (and associated metadata): ``` PAS_API extern pas_large_map_hashtable pas_large_map_hashtable_instance; PAS_API extern pas_large_map_hashtable_in_flux_stash pas_large_map_hashtable_instance_in_flux_stash; PAS_API extern pas_small_large_map_hashtable pas_small_large_map_hashtable_instance; PAS_API extern pas_small_large_map_hashtable_in_flux_stash pas_small_large_map_hashtable_instance_in_flux_stash; PAS_API extern pas_tiny_large_map_hashtable pas_tiny_large_map_hashtable_instance; PAS_API extern pas_tiny_large_map_hashtable_in_flux_stash pas_tiny_large_map_hashtable_instance_in_flux_stash; PAS_API extern pas_tiny_large_map_second_level_hashtable_in_flux_stash pas_tiny_large_map_second_level_hashtable_in_flux_stash_instance; ``` This is unnecessary, and should be changed to help clear the way for future projects. In particular, we should be able to instantiate an arbitrary number of large-map instances (for each of the above types), and associate each large-heap with an arbitrary large map.
