[Suggestion]ArrayEquals supports detection assertEquals(array1, array2) is recommended

### Description of the problem / feature request:

For rule ArrayEquals, assertEquals(array1, array2) is also used to determine whether the array is equalalled . It is recommended that this rule supplement the detection of this case.
This rule is implemented in error_prone_core-2.3.4-sources.jar!\com\google\errorprone\bugpatterns\ArrayEquals.java,
use instanceMethod().onClass(isArray()).named("equals"), argument(0, isArrayType()) to detect the case array1.equals(array2),
use staticEqualsInvocation(), argument(0, isArrayType()), argument(1, isArrayType()) to detect the case Array.equals(array1, array2).
So this rule cannot detect this case: assertEquals(array1, array2)
