[ACPI] Properly return a single alternative in Bus_PDO_QueryResourceRequirements. CORE-12892 CORE-14688 
In ACPI resource descriptors, alternatives are marked with
StartDependent tags. Only the last set is terminated with EndDependent.
Therefore, since we only return the first alternative list for now,
ignore the first StartDependent tag and terminate enumeration at the second.

In the future we will need to build the full set of alternative lists here,
which will also make the unit test succeed fully.

This should fix random resource conflicts and make COM ports usable.

Routine Description:
The PnP Manager sends this IRP to gather information about
devices with a relationship to the specified device.
Bus drivers must handle this request for TargetDeviceRelation
for their child devices (child PDOs).
If a driver returns relations in response to this IRP,
it allocates a DEVICE_RELATIONS structure from paged
memory containing a count and the appropriate number of
device object pointers. The PnP Manager frees the structure
when it is no longer needed. If a driver replaces a
DEVICE_RELATIONS structure allocated by another driver,
it must free the previous structure.
A driver must reference the PDO of any device that it
reports in this IRP (ObReferenceObject). The PnP Manager
removes the reference when appropriate.
Arguments:
DeviceData - Pointer to the PDO's device extension.
Irp - Pointer to the irp.
