acpiexec: Add testability of deferred table verification

Browse Source 
This patch adds testability of deferred table verification mechanism. As
acpiexec uses dynamically allocated root table list from its very early
stage, a change to AcpiReallocateRootTable() is required to allow deferred
table verification mechanism to be triggered in such an environment. Note
that AcpiGbl_EnableTableValidation is still TRUE by default, thus:
1. Developers need to manually set AcpiGbl_EnableTableValidation to FALSE
   for acpiexec to enable this test.
2. For all other OSPMs (Linux, BSDs, etc.), this commit is a no-op.
