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.

Change: Decouple and remove landscape-dependent cargo types. (#11719)

Cargo types of default engines, industries and houses are now specified in terms of label.

Codechange: Use std::array for industry tile cargo acceptance. (#11498)

This avoids use of memcpy/memset to copy or fill.

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

Change: include fmt.h C++ headers in stdafx.h

This to prevent compilation issues between runs with and without precompiled
headers. Also remove the headers from the rest of the code base as they are
not needed there anymore, although they do relatively little harm.

Change: [NewGRF] industry special flag 19 now specifically targets only passenger production, instead of the second cargo of any water-based industry. (#8590)

This behavior is less surprising to NewGRF authors, and may even be intentional behavior for some industries.

Add: [NewGRF] Industry behaviour flag to override second cargo production clamping for water industries when using smooth economy.

Smooth economy is only used when the corresponding setting is enabled and the industries does not use the production callback.
