layers:Connect VK_EXT_validation_flags

Add support for VK_EXT_validation_flags in core_validation.
The only enum currently supported is VK_VALIDATION_CHECK_ALL_EXT which
disables all existing flags in validation. Note that most checks are
still not guarded by flags so that option will only disable the checks
that are guarded by flags.

In testing this I found a bug with AllocateDescriptorSets() where
common state was not updated with the flag enabled so this includes a
fix for that issue as well.
