Disallow multi-dim vector subscript in slang IR (#4277)

Fixes bug #3180
This test verifies the check for illegal swizzle on vector types, whose
element is not a basic Type (int, float).
The check captures the failure within swizzle access on a nested vector
subscript element.
vector<vector<int, 2>, 2> a
int b = a[0].x; // illegal
