Implement Instance->DisconnectDawnPlatform()

This patch implements InstanceBase->DisconnectDawnPlatform() which
can force setting InstanceBase->mPlatform to a member of InstanceBase
instead of a value out of Dawn (e.g.  dawn_platform_ in
WebGPUDecoderImpl in Chromium). We need to explicitly clear
dawn_instance_->mPlatform in Chromium because InstanceBase is always
destroyed after WebGPUDecoderImpl as a shared image object will still
keep a reference of InstanceBase after WebGPUDecoderImpl is destroyed.
