For tensor with non-zero offset, it must be multiplied by element size

Add regression test by creating Tensor in array of 6 elements with offset 3, which before the fix crashed with
```

Summary:
This diff fixes two things which come up when testing a tgif-published pt2 model remote net:
1) Updates isSameDevice to handle meta device to avoid this error:
```
what():  Unsupported device typemeta and meta
Exception raised from isSameDevice at fbcode/caffe2/torch/nativert/executor/PlacementUtils.cpp:20
```

2. Updates xl weight v2 loading logic in Weights.cpp to handle non-TBE xl-weights. Today, we enforce the device is the same for an old weight and new weight when replacing with ModelRunnerAdapter.setAttr(). However, the way we replace non-TBE xl weights is to find any weights on "meta" device and then replace them with their correct weight with real device from xl_weights folder. Therefore, the new weight and old weight will always have different devices and the device check is invalid. I don't think we've run into this so far bc non-TBE xl weights have not been thoroughly tested until now.

Test Plan:
Run MRS you model merge net, which uses non-TBE xl weights. Confirm that before change #1 we get error:
```
Unsupported device typemeta and meta
```
Then after change #1 and before change #2 we get:
```
what():  Mismatched device for merge.user_tower.linear.weight: meta vs cpu
Exception raised from validateValue at fbcode/caffe2/torch/nativert/executor/Weights.cpp:374
```
After change run is successful
