performance: Improve Activation Range entity iteration

Browse Source 
Faster Entity iteration using the chunks full entity list and array access.

Faster chunk lookups skipping the cache, as the pattern of access was not suitable
for cache usage (each request will likely blow cache)

This reduces the cost of Entity Activation Range's initial marking.
