[roll] Roll fuchsia [virtualization] Dynamically choose default guest memory

This sets default guest memory based on host memory. It will reserve
half of host memory up to 2 GiB.

Additionally, this also adds a check in the VMM to ensure guest memory
chosen explicitly isn't larger than host memory (plus a bit of a
buffer). This is required as guest memory is currently non-pageable.

Tested:
Unit tests
Launched a debian VM on an 8 GiB zircon host

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
