Reland "Added relational propertyvalues to GetPropertyValue, which allows UI Automation to access relations from an automation element"

This reverts commit f30471c585171ddd4240258f35b9f31300da7e0b.

Reason for revert: Test failures don't appear to be related in any way. This is accessibility code that hasn't been turned on yet, i.e. it should never be running.

Fixing VARIANT value handling in AXPlatformNodeWin

Handling of VT_BOOL type variants inside AXPlatformNodeWin::GetPropertyValue resulted in wrong boolean logic. The problem was that VARIANT_TRUE has the value of negative one while all other true value types are positive one. Initializing and/or comparing such values was the core issue.

To completely fix the problem a change to the ScopedVariant constructor was added. In order to initialize a variant of type VT_BOOL additional handling was added to the VT_I4 constructor.

Finally, new UIAutomation unit tests are added to validate such parameter passing.

Adding UIA provider callbacks error handling

Unlike straight COM and IA2, UIAutomation provider implementations
are expected to return UIA_E_ELEMENTNOTAVAILABLE instead of E_FAIL.

This change adds the correct error propagation and unit tests to
all currently supported UIA provider interfaces.
