Adds ConfigureResourceConstraintsForCurrentPlatform and SetDefaultResourceConstraintsForCurrentPlatform which configure the heap based on the available physical memory, rather than hard-coding by platform as previous. This change also adds OS::TotalPhysicalMemory to platform.h. The re-land fix the performance regression caused by accidental change in default max young space size.
