Add Support for a new Global Parameter to Query the Sizes of QUIC_STATISTICS_V2

[nibanks]

Describe the feature you'd like supported

A new MsQuic API global GetParam should be added that returns the well-known sizes of each version of the QUIC_STATISTICS_V2 struct.

Proposed solution

Add the new parameter. Support GetParam only. Return hard coded sizes for the various API version sizes.
