Fix #8020: Add missing docking tiles around industry neutral stations

I'm not seeing why a savegame bump is necessary here

It's to fix "broken" saves since SLV_MULTITILE_DOCKS

Suggested change

	if (IsSavegameVersionBefore(SLV_FIX_NEUTRAL_STATION_DOCKING_TILE)) {
	if (IsSavegameVersionBefore(SLV_FIX_NEUTRAL_STATION_DOCKING_TILE) && !IsSavegameVersionBefore(SLV_MULTITILE_DOCKS)) {

to not iterate all stations twice, as now the original IsSavegameVersionBefore(SLV_MULTITILE_DOCKS) block above this fix will be correct.

Other option is to extract the iteration from IsSavegameVersionBefore(SLV_MULTITILE_DOCKS) block and run it unconditionally like AfterLoadRoadStops(), removing the need for the savegame bump

[LordAro]

I'm prepared to say that the few missing tiles don't matter for savegames created between SLV_MULTIDOCK_TILES and now. There's not been a (stable) release between then anyway

Agree with @LordAro here, a bump is not strictly necessary. The missing tiles mean some water industries won't have ships docking in all positions but it's not a game-breaking catastrophe.
On the contrary, a savegame bump will prevent the fix from being backported to 1.10 release, since the savegame version should be frozen in release branches.
