Linkstone runtime support

[aki-ks]

This PR redirects uses of fields annotated with a @Field annotation to the corresponding getter and setter methods. Regular invokes and reflective accesses will be redirected.

Glowkit#20 must be merged for this PR.

[aki-ks]

Linkstone#4 must also be merged and the "annotation" and "runtime" submodules must be published onto a repository.

@aki-ks What is the status of this PR? Do you think it could be reviewed for merge in its current state?

[aki-ks]

Yes, I think so, but you must first make the linkstone-runtime and linkstone-annotations dependency available to the project (publish it on glowstone's maven repo).

[mastercoms]

This is currently blocked by Linkstone getting a working CircleCI build.

Linkstone is now deployed to our Maven repo, through GitHub Actions, so this PR is no longer blocked.
