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

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

Feature: NewGRF properties to set town production effect and multiplier. (#11947)

Town production effect is modelled on town acceptance (growth) effect, and so takes an original cargo slot for behaviour instead of a direct value.

NewGRF feature 0x0B, property 0x1E, takes 1 byte.

Valid values are:
- 0x00 to behave like passengers
- 0x02 to behave like mail
- 0xFF to behave like other cargo (i.e. not produced.)

If not set, town production effect is set based on the cargo label ('PASS' or 'MAIL').

Town production multiplier allows adjusting the amount of cargo produces when Town Production Effect is set, without needing to use callbacks.

NewGRF feature 0x0B (cargo), property 0x1F, accepts a 2 byte (word) value, similar to the cargo capacity multiplier property. The default value is 256 which means 100%, i.e. normal rate.

Codechange: Rename TownEffect to TownAcceptanceEffect.

This makes it clearer that TownEffect only affects acceptance behaviour.

Fix 9602de4: FinaliseCargoArray did nothing. (#11839)

`CargoSpec::Iterate()` deliberately skips invalid cargo types, but `FinaliseCargoCarry()` is only interested in them.

Codechange: Use comparator struct to sort cargo ID by predefined sort order.

This allows reuse of the comparator where a typename is used instead.

Fix #11315: Sort industries and cargoes by name* in industry chain window.

*Cargo types are sorted by the normal method so it's not strictly alphabetical.

Codechange: Rename INVALID_CARGO to INVALID_CARGO_BITNUM

... to avoid future ambiguity.

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

for i in `find src -type f|grep -v 3rdparty/fmt|grep -v 3rdparty/catch2|grep -v 3rdparty/opengl|grep -v stdafx.h`; do sed 's/uint16& /uint16 \&/g;s/int8\([ >*),;[]\)/int8_t\1/g;s/int16\([ >*),;[]\)/int16_t\1/g;s/int32\([ >*),;[]\)/int32_t\1/g;s/int64\([ >*),;[]\)/int64_t\1/g;s/ uint32(/ uint32_t(/g;s/_uint8_t/_uint8/;s/Uint8_t/Uint8/;s/ft_int64_t/ft_int64/g;s/uint64$/uint64_t/;s/WChar/char32_t/g;s/char32_t char32_t/char32_t WChar/' -i $i; done

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.

Codechange: Remove CargoSpec::multipliertowngrowth which is unused (#9701)

This is set by cargo property 19.
This property is only implemented in TTDPatch.

Fix #9440: negative cargo payments not being handled right

Cargo payments were stored as unsigned integer, but cast to int64 during
application of inflation. However, then being multiplied with a uint64
making the result uint64. So in the end the payment that should have been
negative becomes hugely positive.

Fix: Resolve cargo-types of default vehicles via their cargo label.

Default vehicles now behave as if they had a cargo translation table. This fixes default vehicles carrying seemingly random cargos, if NewGRF industry sets are present.
This behavior is disabled, when a NewGRF touches any of the cargo-type or refitting properties. In that case it's up to the NewGRF to define its own cargo translation table.

Fix #9097: Upper 16 bits of cargo base payment rate were discarded. (#9098)

NewGRF spec says that base payment rate is 32 bits, but it was loaded into a 16 bit variable. This value is loaded into Money variable after inflation is applied.
