Fix a258833: Don't invalidate station list on vehicle load/unload. (#12112)

a258833 fixed a bug but as a result causes the station list to be rebuilt every time (once per game tick) a vehicle loads/unloads.

Instead just mark the window for redraw.

Adds a function for Scripts to get the number of helipads of an airport type.

Fix: NewGRF roadstops were ignored if only in default class. (#12089)

If a NewGRF defines roadstops in the default class and no other classes are defined, they would be ignored and not selectable.

Codefix: Incorrect storage type in cargo field of industry cargo chains window. (#12051)

`supp_cargoes` and `cust_cargoes` actually contains a column index, however this index is always stored at the indexed position...

Replace with a bitmask instead, which stores if the column indices are linked.

Codechange: Don't scan vehicle pool to find targeting disaster vehicle when deleting any vehicle. (#12064)

* Codechange: Don't scan vehicle pool to find targeting disaster vehicle when deleting any vehicle.

When deleting a vehicle, the vehicle pool is scanned to find a targetting disaster vehicle. With lots of vehicles this can take some time, especially when deleting multiple consecutive vehicles.

Disasters vehicles can actually only target road vehicles. Store the DisasterVehicle index in the road vehicle, so that no pool scan is necessary.

* Change: Small UFOs no longer target a vehicle which is already a target.

Change: Avoid adjacent fence fields.

This restores pre-r23168 behaviour of only a single fence between adjacent fields.

Change: Draw north-side farm fences/hedges/walls on tile edge, instead of 1/16th in.

This matches original TTD drawing behaviour, which is what the original baseset sprites are designed for, and avoids alignment issues (which are more problematic with high detail 4x sprites.)

Fix: Industry tiles and houses could accept incorrect cargo types. (#12062)

Ensure the default label is cleared when NewGRFs set industry tile or house acceptance.

This was missed by #12053.

Remove: setting "no_http_content_downloads" (#12058)

As we now use HTTPS, it is very likely this will work on most systems.
For systems that do have HTTPS blocked, it will fail instantly,
and it will fallback to TCP anyway. That makes this setting no longer
very useful.

Fix #12052: NewGRFs clearing industry cargo slots could fallback to default instead of empty. (#12053)

Ensure the default label is cleared when NewGRF sets a produced/accepted cargo slot, so that default fallback isn't used.

Change: Include count of stations per cargo type in station cargo filter.

Cargo types with no stations are shaded to make the list clearer.

Change: Replace long list of cargo filter buttons with a multi-select dropdown list.

As before, hold ctrl while clicking on an item to toggle selections.

Codechange: Add method to replace the content of a dropdown menu.

If necessary the dropdown list window will be resized and scrollbar enabled/disabled.

Codechange: Add parameter to persist dropdown menus.

If a dropdown menu is set to persist, it will not close when an item is selected. It will close as normal if the window loses focus.

Closing the list is the responsibility of the caller.

Fix #12012: Crash when opening orders of another company. (#12013)

Orders window changes tooltip depending on vehicle type but did check if widget exists.

Fix 2fd90960: Missing default vehicles and industry acceptance/production. (#12000)

* Fix 2fd90960: Missing default vehicles and industry acceptance/production.

Some default definitions are used across multiple climate types and relied on climate-independent cargo slot even though they specified a climate-dependent cargo type.

Add MixedCargoType that indirectly allows multiple labels to be specified for these.
