add ConstantConditions.SUGGEST_NULLABLE_ANNOTATIONS to inspections. This inspection flags code that mixes `@Nullable` values and non-`@Nullable` params. Such code is likely erroneous and a common place for NPEs to hide.

add ConstantConditions.SUGGEST_NULLABLE_ANNOTATIONS to inspections.
This inspection flags code that mixes @nullable values and non-@nullable params.
By Square Java convention, we treat unannotated method params as non-null by default.
Thus, code that mixes nullability in this way is likely incorrect, and creates an easy place for NPEs to hide.
With this change, a method call that passes a value IntelliJ determines to be possibly null into a method parameter not annotated as @nullable will be highlighted with the warning text,
Argument '<some possibly-null expression>' might be null but passed to non-annotated parameter.
