Support regex-style matching for Any and Oneof (#82853)
pseudo.any is a wildcard node that can be matched with any fx node with arbitrary number of inputs and outputs.
For example, to match relu followed by one fx node:
```
def pattern(a):
y = a.relu()
z = torch.ops.pseudo.any(y)
return z
```
pseudo.oneof is a special node that can be matched with a fx node whose target is in the permissible list.
`targets` must be be a list of qualified name for operators, e.g. ["operator.add", "torch.sigmoid",
"torch.ops.aten.foo", "torch.ops.prims.bar"]
For example, using following pattern with pseudo.oneof
```
def pattern(a):
y = a.relu()
z = torch.ops.pseudo.oneof(y, targets=["relu", "torch.sigmoid", "operator.add"])
return z
```
It will have 3 matches in the following function
```
def forward(y):
z = y.relu()
x = z.relu() # first match
x = x.relu()
x = torch.sigmoid(x) # second match
x = x.relu()
return x + 1 # third match
```
