Support instrumentation for Vert.x web and core 5.x

[sharvath-newrelic]

Overview

Adds vertx-core-5.0.0 and vertx-web-5.0.0 instrumentation modules to support applications running on Vert.x 5. Vert.x 5 introduced breaking API changes across its async and HTTP layers, so new modules were required rather than extending the existing 4.x ones.

While many files were able to be cleanly ported from previous Vert.x instrumentation, a few areas required changes.
Some areas of note:

• Async token propagation: Listener was replaced by Completable in FutureImpl's internals. The tryComplete/tryFail pair was unified into completeInternal, and a new onComplete(successHandler, failureHandler) weave point wraps both handlers at registration time via CallbackWrapper, to help ensure async continuations run in the correct transaction context whether the future resolves synchronously or later.
• HTTP client: The PromiseInternal-accepting overload of doRequest was removed in 5.x, replaced with a Future-returning variant with a different signature. The weave point moved to the public request(RequestOptions) method. Attaching the result handler was delegated to a utility method (VertxCoreUtil.attachRequestResultHandler) because calling onComplete directly inside a weave method body triggered an IncompatibleClassChangeError at startup.
• Blocking execution: executeBlocking changed from Handler<Promise<T>> to Callable<T>. The token wrapper was updated: (PromiseHandlerWrapper → CallableWrapper), and the now-removed setResultHandler was dropped.

Testing

Both modules mirror the test suites of the prior Vert.x instrumentation modules with additions made to support the 5.x API.
