Internally allocates a heap buffer of the requested size and passes it to the parent LinearAllocator. Unlike LinearAllocator, ArenaAllocator owns its storage and releases it automatically on destruction. All LinearAllocator operations (Alloc, AllocOne, AllocArray, GetMarker, Rewind, Reset) are available through inheritance.
