[PATCH v5 01/27] build: add build defines for component name and class

[Anatoly Burakov]

From: Bruce Richardson <bruce.richardson at intel.com>

When building each component, pass in -D flags to define for it the
component class and name. This allows any files which may be used
multiple times to identify what component is including them.
