Add require static entries for annotations.

This fixes warnings that arise when javac goes looking for, e.g., `DoNotMock.value()`, which it can't find if the Guava module is not permitted to access `error_prone_annotations`.

The warnings don't come up with JSpecify annotations (or perhaps J2ObjC annotations?), but it seems reasonable to declare those dependencies, too: If we were building Guava as a "normal" module (instead of [building its `module-info` separately](https://github.com/google/guava/blob/6dcc4ef29811962cfbcdbc888a0dc9c4a1efc1a3/guava/pom.xml#L101-L141)), javac would _force_ us to declare them.

Fixes #7732

RELNOTES=Fixed annotation-related warnings when using Guava in modular builds. The most common such warning is `Cannot find annotation method 'value()' in type 'DoNotMock': ...`.
