Add resources_lock_ lock_guards to avoid race condition when loading robot_description through topic (backport #1451)

[mergify]

As reported in #1442, loading the robot_description through the topic will cause a segmentation fault or some undefined behaviors as the read and write methods real-time methods are continuously executed, and when the robot description is received and the resource_manager is to be initialized, there is no lock_guard of recursive mutex resources_lock_, which should avoid the RM to execute the components when they are changing state or being loaded and initialized

Fixes #1442
