Physical segments were still allocated from global command context mempool. This leads to very high memory usage when activating large VG (vgchange). (Memory usage was about 2G when >3000LVs). Fix it by properly using vg->vgmem private pool, so all the memory is released early. New memory pool parameter is needed here for pv_split_segment function. Also fix the same problem in some minor allocations (vg description, lv segment split).
