[NFC] Make attrs type for AOT the same as JIT (#5702)

The main problem why it is easier to change the type for AOT compilation
is that `json` module has a limitation on serialization/deserialization
(`dumps/loads`) of `tuple` type, which will be processed as `list`. In
general, I can write a custom serialization/deserialization function,
but this will also need to be done by everyone who works with the Triton
cache directly (this may need to be done in PyTorch), which seems
undesirable.
