[edk2-staging/EdkRepo] [PATCH] EdkRepo: Allow pin file to be checked out when combo is not in project manifest

["Desimone, Ashley E" <ashley.e.desimone@intel.com>]

When a pin file is based on a combo that is not in the project
manifest file but otherwise matches the project print a warning
instead of throwing and exception and allow the pin to be
checked out.
