  [clang-tidy] Fix false positive for cppcoreguidelines-pro-bounds-pointer-arithmetic (#127394)

this PR fixes #126424
for `ArraySubScriptExpr`, `hasBase` Matcher will get right operand when
it is not integer type, but is not for sure that left operand is integer
type. For the example code below `hasBase` will get `r` for the
Subsequent matching and causing false positive.
```
template <typename R>
int f(std::map<R*, int>& map, R* r) {
  return map[r];
}
```
so is needed to see if index is integer type to avoid this situation.
