Solaris/OpenBSD/FreeBSD: [heap] Uncommit unused large object page memory.

Port d61a5c376ba51145dc4684e39d5d3a9ce75bcfa6

Original commit message:

    As a first step I uncommit the memory on the main thread. Also
    to measure impact and stability of that optimization. In a
    follow-up CL, the uncommitting should be moved on the concurrent thread.
