Switch hasattr check from compile to compiler (#5096)
torch.compile introduced in torch 2.0 but torch.compiler was introduced
in torch 2.1, this fixes issues for those building with torch 2.0 like
the A6000 builds.
```
>>> torch.__version__
'2.1.0+cu121'
>>> hasattr(torch, "compile")
True
>>> hasattr(torch, "compiler")
True
>>> torch.__version__
'2.0.0+cu117'
>>> hasattr(torch, "compile")
True
>>> hasattr(torch, "compiler")
False
```
