Ahead-of-time compilation for process models

[tobiasschaefer]

Currently, process models are parsed at runtime during startup.

Idea: use the ahead-of-time compilation concept of Micronaut to parse the process models during build time and create a Java-Code representation, see org.camunda.bpm.model.bpmn.Bpmn with methods like createProcess.

This will reduce the startup time.

Todo: first check if this optimisation is really worth the effort.

Comment from @StephenOTT in #1: Note that the fluent API does not support all aspects BPMN. So as a result you need to manually generate many of the objects at a low level of the API. (Again went down this path as well for other use cases)
