  [analyzer] Fix crash on using `bitcast(<type>, <array>)` as array subscript (#101647)

Current CSA logic does not expect `LazyCompoundValKind` as array index.
This may happen if array is used as subscript to another, in case of
bitcast to integer type.

Catch such cases and return `UnknownVal`, since CSA cannot model
array -> int casts.

Closes #94496
