[roll] Roll fuchsia [kernel][x86] Fix PML4 boundary prepopulation and cleanup

Fixes boundary alignment bugs in x86 page tables that caused incorrect
PML4 entries to be skipped during prepopulation (InitShared/InitUnified)
and cleanup (DestroyIndividual). This resolves kernel panics caused by
dynamically allocating unpopulated top-level entries or leaking present
page tables at process teardown when mapping at the end of the shared
VMAR.

Add regression tests to verify these boundary mapping and teardown
behaviors.
