Prepare support for Dynamic Instrumentation (#4492)

Prepare the Node.js tracer to be used with the Dynamic Instrumentation product
(DI).

Probes are added as breakpoints using the V8 Inspector Protocol. The inspector
runs in a worker thread and will pause the main thread temporarily while
gathering the required information related to the probe (as of this commit no
information is gathered, but this is a required step once we start to gather
the local state snapshot).

DI features included in this commit:
- Support for line based log probes
- Support for loading probes via Remote Configuration
- Support for sending probe status to the debugger-backend
- Support for sending log data to debugger-backend

Please note, that with this commit it's still not possible to use DI with the
Node.js tracer as support for using the Node.js tracer with DI has not yet been
enabled in the Datadog UI.
