[FEA][torchinductor-EVT] Allow function source code to be passed directly to EVT tracer

[mlazos]

Is your feature request related to a problem? Please describe. At https://github.com/NVIDIA/cutlass/blob/5e497243f7ad13a2aa842143f9b10bbb23d98292/python/cutlass/epilogue/epilogue.py#L117

the trace(..) API takes in a function. The main issue here is that when dynamically defining a python function like so

fn = exec("""
def fn(x):
  return x
"""

extracting the source using inspect.getsource here fails.

This is how inductor generates the python source in essence (it generates a function string) so this does signature doesn't work.

Describe the solution you'd like Modify the signature of trace to take the function source string directly.
