This fixes the Daydream Dashboard issues so that if Chrome is simply
stopped/started in VR without any intents, Chrome stays in VR.

Also makes resuming Chrome from DD home way faster if Chrome was
already in VR.

This patch whitelists all our supported properties. Any property that
is not supported will return a base CSSStyleValue. This ensures that
we don't accidentally produce unexpected results for properties that
we haven't tested it.

We also add a few new properties to support, bringing the total number
of property tests to 50. We also remove support for 'z-index' because
it uses <integers> which we don't support yet.

transition-duration is failing tests because we currently convert
ms to seconds when we compute, which is incorrect.

Some paint/layout tests depend on properties that are not whitelisted,
so we've changed them:
- border-radius -> margin-left
- align-items -> empty-cell

This CL fixes the calculation of the new action container's width and

Introduce new code patterns to improve the likeliness that future
changes to the elements of PrefetchItemState will be properly handled.

A new |kOrderedPrefetchItemStates| complements the enum definition by
providing the full listing of existing states. A new test also checks
that changes to the enum are reflected in this listing.

The implementation of GetAllStatesExcept was updated to use this
official state list and accept a collection of states to filter from its
result. New calls to this function were also added from tests where
created a local listing of arbitrary states, what should guarantee that
new or changed state values would have to be dealt with.

Finally uses of `default` in switch blocks for PrefetchItemState were
replaced with the full listing of all possible states so that build
errors would guide the proper handling of all states.

-This CL also (finally) includes an update to the ConvertProcessMitigationsToPolicy() API.
 MS ran out of bits in the DWORD64 for process mitigation flags, so related APIs can now
 take in a two-element array of DWORD64s.  The second element is for "*POLICY2*" mitigation
 flags (defined in WinBase.h).

**Any downstream users of this sandbox API will need to update their code to always
