[roll] Roll fuchsia [kernel][x86] Ensure that stale global TLB entries don't persist

This changes address a bug in x86 kernel start-up code that could have
permitted stale global TLB entries to persist into the creation of its
virtual address space. We should disable PGE before installing our new
root to flush such entries, and then only re-enable it once the new root
page table is installed so that no more stale entries have a chance to
be created.
