feat: do not run nodejs agent for unsupported node runtimes (#1528)

At the moment, nodejs agent will import all it's dependencies when it
starts. Those might pull in code that is not compatible with old node
runtimes, and cause an exception in agent code.

This PR makes it so that the agent is only loaded if the nodejs version
is supported, and silently catch and ignore any exception from the
agent.

This PR extract the compiling of the nodejs agent to a separate docker
build stage, a bit simplifying the dockerfile


If the nodejs runtime version was detected in language detection, the
instrumentation device should not even be injected and the agent should
not be loaded. However, if the runtime details is not detected, or some
other situation causes the agent to run on an old node runtime, the
agent should handle it and not cause any issues for application
