Respect the Better Save Menu enable toggle (#6970)

RegisterBetterSave registered its VB_LOAD_SAVE_MENU and VB_DRAW_SAVE_MENU
hooks unconditionally, and hardcoded the save/continue text overrides to
`true`, so the feature applied regardless of the enable checkbox and
toggling it off did nothing. CVAR_BETTERSAVE_VALUE was defined but never
read.

Gate all five hooks on CVAR_BETTERSAVE_VALUE (COND_VB_SHOULD for the two
vanilla-behavior hooks, the condition arg for the three OnOpenText hooks).
RegisterShipInitFunc already re-runs RegisterBetterSave when CVAR_BETTERSAVE
changes, so the COND_* macros unregister the hooks when it is off and
re-register them when it is on.
