wsl/libhsakmt: move local heap and va_Mgr from device to thunk runtime

In multi-GPU, local heap space is shared between all GPUs, not belongs to
specific one GPU, so move it from wddm device (which presents a specific GPU)
to thunk runtime which has gloable view, can manage local heap for all GPUs.
