  Disable GPUConnectionToWebProcess::createRemoteGPU if WebGPU is not enabled

Reviewed by Myles Maxfield.

Have the GPUConnectionToWebProcess keep a boolean to keep track of whether
WebGPU is enabled for any Page in that process.  Update the boolean when
adding or removing a Page.  If we get a message to use the entry point of
WebGPU and WebGPU is disabled, then terminate the web content process
from which the message came instead of creating a RemoteGPU.
