Experimental optimization for the segment reclamation logic.
...
The goal is to improve efficiency of finding an abandoned segment that contains free space of the required size.
This change adds a free space bitmask to the segment object. More optimal place for the bitmask could be in the arena (i.e. extend the arena’s bitmask for abandoned segments to include size information too).

Experimental improvements to reduce memory usage
...
1. Prefer to use more loaded pages when allocating
2. Add an option to restrict unbounded heap growth and allow the excessive memory allocations to be re-used by other threads
