kernel-yocto: provide debug / summary information for metadata

Browse Source 
It was mentioned that when developing a BSP, the information about what
definition was used, or what fragments have been applied is not obvious
and requires looking at the code.

With this change, we can trigger a full summary of the meta data gathering
phase when KCONF_AUDIT_LEVEL > 0.

Sample output follows:

   NOTE: do_kernel_metadata: for summary/debug, set KCONF_AUDIT_LEVEL > 0
   NOTE: kernel meta data summary for qemux86-64 (standard):
