[cudagraph] fix verbose graph logging (#126694)

According to the [doc](https://docs.nvidia.com/cuda/cuda-runtime-api/group__CUDART__TYPES.html#group__CUDART__TYPES_1g0907ca7a1e7d0211b71ee49c5403072b):

`1 << 10` is not the most verbose flag. it is just one flag to add node handles and every kernel function handle to output. `1 << 0` is the most verbose flag, under the name `cudaGraphDebugDotFlagsVerbose`.

Here is an example of graph, dumped with `1 << 10`:

```dot
digraph dot {
subgraph cluster_1 {
label="graph_1" graph[style="dashed"];
"graph_1_node_0"[style="solid" shape="rectangle" label="0
MEM_ALLOC
node handle: 0x000055D2889750F0
"];

"graph_1_node_1"[style="bold" shape="octagon" label="1
_Z3addPhS_S_m
node handle: 0x000055D288979A20
func handle: 0x000055D288978D40
"];

"graph_1_node_2"[style="solid" shape="trapezium"label="2
MEMCPY
node handle: 0x000055D28897A130
(DtoH,1024)
"];

"graph_1_node_3"[style="solid" shape="rectangle" label="3
MEM_FREE
node handle: 0x000055D2889890C0
"];

"graph_1_node_0" -> "graph_1_node_1";
"graph_1_node_1" -> "graph_1_node_2";
"graph_1_node_2" -> "graph_1_node_3";
}
}
```

The same graph dumped with `1 << 0`:

```dot
digraph dot {
subgraph cluster_1 {
label="graph_1" graph[style="dashed"];
"graph_1_node_0"[style="solid" shape="record" label="{
MEM_ALLOC

| {{bytesize | dptr} | {1024 | 0x0000000A02000000}}
}"];

"graph_1_node_1"[style="bold" shape="record" label="{KERNEL

| {cooperative | 0}
| {priority | 0}
}"];

"graph_1_node_2"[style="solid" shape="record" label="{
MEMCPY
| {{ID | node handle} | {2 (topoId: 1) | 0x000055D28897A130}}
| {kind | DtoH (DEVICE to HOST PAGEABLE)}
| {{srcPtr | dstPtr} | {pitch | ptr | xsize | ysize | pitch | ptr | xsize | ysize} | {0 | 0x0000000A02000000 | 0 | 0 | 0 | 0x000055D287CA6DB0 | 0 | 0}}
| {{srcPos | {{x | 0} | {y | 0} | {z | 0}}} | {dstPos | {{x | 0} | {y | 0} | {z | 0}}} | {Extent | {{Width | 1024} | {Height | 1} | {Depth | 1}}}}
}"];

"graph_1_node_3"[style="solid" shape="record" label="{
MEM_FREE
| {{ID | node handle} | {3 (topoId: 0) | 0x000055D2889890C0}}
| {{dptr} | {0x0000000A02000000}}
}"];

"graph_1_node_0" -> "graph_1_node_1" [headlabel=0];
"graph_1_node_1" -> "graph_1_node_2" [headlabel=0];
"graph_1_node_2" -> "graph_1_node_3" [headlabel=0];
}
}
```

They are based on
