inductor: fix convert_shape_to_symint (#93349)
Fixes https://github.com/pytorch/pytorch/issues/93833.
When `lst` is composed of a mix of static shapes and `sympy.Expr`, convert static shapes to ints and `sympy.Expr` to `symints`.
The old logic required that all of the elements of `lst` be static and it can then convert them to ints.
