Prior to this commit, the total device memory could be queried through the `DeviceAPI` interface, but the currently available device memory could not. This functionality may be useful for debugging, or for validating available memory prior to model execution. This commit implements the property `Device.available_global_memory`, which queries the `DeviceAttrKind::kAvailableGlobalMemory`. Support for this query, like all device attribute queries, may vary across different backends, and will return `None` for backends that do not support this query. This commit only currently implements support for `kAvailableGlobalMemory` for TVM's Cuda backend.
