Add apiguardian-api runtime dependency to satisfy ART's internal runtime annotation loader (#306)

Essentially, `@API` is added to most of the JUnit 5 annotations. This is an annotation
from a library called "API Guardian", which declares a `RUNTIME` visibility.

For Android specifically, this visibility makes it eligible for native annotation scanning
when calling `Class.isAnnotationPresent()` on any of the JUnit 5 annotations with that meta-annotation.
The problem is that JUnit Jupier declares its transitive dependency as "compile-only",
causing `@API` to be absent at runtime. This creates a log statement every time an annotation
is queried, causing very noisy logs.

The fix is to submit API Guardian as a runtime-only dependency to the instrumentation core.

Resolves #291.
