Set configuration manager (#11534)
* Add the setter for the ConfigurationManager.
Also remove the implementation getter.
* Remove uses of ConfigurationMgrImpl.
Promote the reboot count, boot reason, and operational hours methods
to the ConfigurationManager interface.
* Add a static instance getter to the ConfigurationManagerImpl.
* Set the default ConfigurationManager instance in the platform manager.
* Update the tests to set a ConfigurationManager instance.
* Allow subclasses of the platform ConfigurationManagerImpls.
* Re-fix Ameba's ConfigurationManagerImpl.
* Restyled by clang-format
* Improvements from pull request comments.
* Add VerifyOrDie to the ConfigurationMgr getter.
* Pass a pointer rather than a reference to ConfigurationMgr.
* Explicitly default the instance pointer to nullptr.
* Move the singleton implementation out of each platform into a shared file.
* Update Ameba platform to remove the new uses of ConfigurationMgrImpl.
