Codechange: Use `GetVisibleRangeIterators()` in more places. (#12190)

This replaces more first/last index calculation, along with indexed array/vector access, with iterator access instead.

Codechange: Use vehicle tile hash to build depot vehicle list. (#12186)

This avoids iterating the entire vehicle pool.

Codefix: DrawEngineList does not accept EngineID.

Replace min/max parameters of DrawEngineList with scrollbar reference, and use iterators instead of indices.

Codechange: Off-by-one in colour gradient initialisation.

Remap sprites start with a count byte followed by 256 entries, but
SetupColoursAndInitialWindow did not take account of this extra byte and
therefore started at palette index 0xC5 instead of 0xC6. This caused the
first colour of each gradient to be incorrect and all shades were actually
1 step lower in the gradient than indicated.

Codechange: Remove direct access to _colour_gradient.

Access is now through GetColourGradient, which ensures parameters are in range.

Change: Use bitmap for free unit ID generation. (#12165)

This improves performance of finding the next free unit number for a vehicle.

Based loosely on pool's used slot bitmap.

Fix d3c673e: Don't defer OnResize() after ReInit() (#12174)

Some windows resize themselves during painting and issue ReInit(). In this case deferred OnResize() causes a visible glitch as the event is handled on the next redraw.

Revert #11993: new number format system does not and cannot work for CJK languages

There are too many intricacies that I am unaware of that are popping up after
asking whether things are right or not.
I do not want to keep playing whack-a-mole, so just revert the whole thing.

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.
