…ble plan_nereids_dump

Cherry-pick of apache#66371.

Adapted for branch-4.1: this branch has no VariableMgr.REMOVED_SESSION_VAR_NAMES
compatibility list, so only the SessionVariable part is picked. `SET plan_nereids_dump
= ...` therefore reports ERR_UNKNOWN_SYSTEM_VARIABLE on this branch instead of being
silently ignored. Replaying an old global-variable edit log or image entry is
unaffected: VariableMgr.replayGlobalVariableV2 logs and skips unknown variable names.

(cherry picked from commit e308b6a)
