Revert "[LayoutNG] Heap allocate algorithms to save stack space."

This reverts commit ba345fef.

Reason for revert: Now that win32 stack has increased to 1.5MB[1] we
can reclaim perf. and revert this change.

Original change's description:
> [LayoutNG] Heap allocate algorithms to save stack space.
> 
> This moves NGLayoutAlgorithm onto the heap using partition alloc.
> 
> This (in mac-64bit) reduces the stack space from 1392 -> 864 bytes
> which is the same as legacy.
> 
> From pinpoint data, this only seems to have a slight performance
> regression.
> 
> A follow up patch will be sent so which performs a refactoring, so that
> this patch can be a simple cherry pick with the beta branch.
>
