Removes the deprecated Babylon::Graphics::DeviceUpdate compatibility shim and updates samples/apps/tests to rely solely on Device::StartRenderingCurrentFrame() / Device::FinishRenderingCurrentFrame() for frame synchronization.

Changes:

• Deleted DeviceUpdate and Device::GetUpdate() from the public graphics device header.
• Removed DeviceUpdate usage across unit tests and sample applications.
• Updated ExternalTexture documentation examples to no longer reference DeviceUpdate.
