sched/topology: Rename SD_SHARE_PKG_RESOURCES to SD_SHARE_LLC
SD_SHARE_PKG_RESOURCES is a bit of a misnomer: its naming suggests that
it's sharing all 'package resources' - while in reality it's specifically
for sharing the LLC only.
Rename it to SD_SHARE_LLC to reduce confusion.
[ mingo: Rewrote the confusing changelog as well. ]
