   src/runtime/crt/host/crt_config.h so that it doesn't diverge from
   the template
 * bring template crt_config.h inline with the one actually in use
  * rename to MAX_STRLEN_DLTYPE
 * Create a dedicated TVM-side host crt_config.h in src/runtime/micro

* Modify Transport infrastructure to work with Project API

* Add host microTVM API server

* Zephyr implementation of microTVM API server

 * move all zephyr projects to apps/microtvm/zephyr/template_project

* consolidate CcompilerAnnotator
