[ty] Limit argument expansion size for overload call evaluation (#20041)
## Summary

This PR limits the argument type expansion size for an overload call
evaluation to 512.

The limit chosen is arbitrary but I've taken the 256 limit from Pyright
into account and bumped it x2 to start with.

Initially, I actually started out by trying to refactor the entire
argument type expansion to be lazy. Currently, expanding a single
argument at any position eagerly creates the combination (argument
lists) and returns that (`Vec<CallArguments>`) but I thought we could
make it lazier by converting the return type of `expand` from
`Iterator<Item = Vec<CallArguments>>` to `Iterator<Item = Iterator<Item
= CallArguments>>` but that's proving to be difficult to implement
mainly because we **need** to maintain the previous expansion to
generate the next expansion which is the main reason to use
`std::iter::successors` in the first place.

Another approach would be to eagerly expand all the argument types and
then use the `combinations` from `itertools` to generate the
combinations but we would need to find the "boundary" between arguments
lists produced from expanding argument at position 1 and position 2
because that's important for the algorithm.

Closes: https://github.com/astral-sh/ty/issues/868

## Test Plan

Add test case to demonstrate the limit along with the diagnostic
snapshot stating that the limit has been reached.
