EmbeddedPkg/PrePiLib: Add FFS_CHECK_SECTION_HOOK when finding section
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4152
EmbeddedPkg/PrePiLib provides the service of finding sections based on
the input SectionType. But sometimes there maybe multiple sections
with the same SectionType. FFS_CHECK_SECTION_HOOK is a hook which can
be called to do additional check.
