Re-types plugin_job_election()/plugin_prepare_allocation()/
plugin_commit_decision() from (void* arg, ...) to (xce_sched_core_t*
core, ...), iterating core->plugins directly instead of deriving it
from a normal-mode-only driver struct -- mirroring
plugin_begin_session()/plugin_end_session()'s already-completed
migration.
Adds a new, honestly-typed xce_sched_plugin_t.core field, set by both
plugin_register() (normal mode) and plugin_register_core() (simulation
mode, closing a gap left since bug-1825 where this path set nothing).
The existing plugin->sched field and its plugins/fcfs.c legacy
consumer are left untouched.
Necessarily updates the 4 existing normal-mode call sites (scheduler.c,
resource.c, schedobj.c) to pass &(...->core) -- a C signature migration
cannot keep the build green without touching every caller in the same
commit; each fix is a minimal argument wrap with no algorithm change,
matching design.md's own Implementation Notes for this component.
