fru: Add support to insert hot-plug PDRs into repository

This API helps to insert PDRs that are added or modified
during concurrent maintenance operations into the PDR repository.
The function assigns a new record handle (based on the last
BMC side PDR handle) and appends the provided PDR entry to the
repository.

Tested By: Tested and it successfully builds with -Doem-ibm=disabled
