Expose API-specific row alignment values (#2151)

* Added function to IDevice that retrieves the row alignment for the particular API; Added rowDstStride argument to copyTextureToBuffer and changed D3D12 footprint row pitch to check that the user-supplied stride is correctly aligned before assigning to the footprint's row pitch

* Changed alignment from Uint to size_t
