`RedundantOverride` does not flag redundant `Object#hashCode` override

Consider the following code:

```java
public final class RedundantOverrideHashCode {
@Override
public int hashCode() {
return super.hashCode();
}
}
```

The `RedundantOverride` bug checker doesn't suggest dropping the redundant `#hashCode` override.

RedundantOverrideHashCode.java
```

It returns no match since `Object#hashCode` has the `native` modifier (see [line 91-94](https://github.com/google/error-prone/blob/56dfc7912b6300bae8706b241c19054a582be79b/core/src/main/java/com/google/errorprone/bugpatterns/RedundantOverride.java#L91-L94)). However, naively excluding the native modifier (something like `Sets.difference(superMethod.getModifiers(), Set.of(Modifier.NATIVE))`) is also not sufficient because of the `@HotSpotIntrinsicCandidate` annotation in `Object#hashCode` (see [line 100-107](https://github.com/google/error-prone/blob/56dfc7912b6300bae8706b241c19054a582be79b/core/src/main/java/com/google/errorprone/bugpatterns/RedundantOverride.java#L100-L107)).

My failing test in `RedundantOverrideTest`:

```java
@Test
public void overridingHashCode() {
testHelper
.addSourceLines(
"Test.java",
"class Test {",
" // BUG: Diagnostic contains:",
" @Override public int hashCode() {",
" return super.hashCode();",
" }",
"}")
.doTest();
}
```
