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.
