Record source/line info in SourceRange and report in highlight (#20898)
Summary:
Resolves https://github.com/pytorch/lockdown/issues/29
Examples:
```
import torch
torch.jit.script
def foobar(x):
return torch.blargh(xyz)
==
RuntimeError:
object has no attribute blargh:
at compile.py:5:12
torch.jit.script
def foo(x):
return torch.blargh(x)
~~~~~~~~~~~~ <--- HERE
```
It also gets the correct column number in the case where the original source file has common leading whitespace in front of the callable:
```
import torch
with torch.no_grad():
torch.jit.script
def foo(x):
return torch.blargh(x)
==
RuntimeError:
object has no attribute blargh:
at compile_leading.py:6:24
torch.jit.script
def foo(x):
return torch.blargh(x)
~~~~~~~~~~~~ <--- HERE
```
