b55fc3d773 mapgen: drop mapgen id from child mapgens.
This id must be owned by the child mapgen and never be set to a misc value by a developer

Also use nullptr in some places

Valleys mapgen code rewrite (#8101)
Shorter, simpler, clearer and more consistent with other mapgens,
while preserving functionality.
Base terrain shape is unchanged.
With the 'vary river depth' option disabled, river surface level
is unchanged.
Behaviour of the 4 heat/humidity/river depth options is very
slightly changed due to bugfixes and code cleanup (the mapgen is
'unstable').
Apply heat and humidity gradients above water_level instead of
above y = 0.

Change mapgen order to ores > dungeons > decorations (#7656)
Previously dungeons > decorations > ores.
Decorations depend on the node they are placed on, and ore types are
increasingly able to place large continuous volumes of nodes, such as
strata. Decorations are increasingly being used underground.

The new order avoids a node being changed by ore generation after a
decoration has been placed on it.
The new order also avoids ores appearing in the walls of a dungeon if
the wall nodes match the local stone node.

Mgvalleys: Make river depth variation and humidity drop optional (#7532)
Add 2 new mapgen flags to make river depth variation and humidity drop
with altitude independently optional, instead of both being enabled by
the 'humid rivers' flag.

Simplify and clarify related code by removing a low priority
optimisation regarding 't_heat'.
Remove unnecessary optimisation bools and use spflags directly instead.
Improve and fix documentation in settingtypes.txt.
A few minor code cleanups.

Mapgen flags: Add 'biomes' global mapgen flag (#7355)
Previously the only way to disable biomes was to 'clear' the registered
biomes in a mod, but this method causes large amounts of unnecessary
processing:
1. Calculation of 4 2D noises.
2. Looping through all nodes of a mapchunk replacing nodes with identical
nodes.
The new flag disables those operations.

Mapgen caves: Re-order generation to fix cavern bug
Previously, caverns confused tunnel generation causing biome top and filler
nodes to appear in caverns.
Split 'generateCaves()' into 2 functions to separate tunnel and large
randomwalk cave generation.
In each mapgen re-order cave generation to generate tunnels before caverns.

Mgvalleys: Code cleanup
Split some long lines.
Edit comments.
Remove unnecessary comments and unnecessary commented-out code.
Use std::fmax/fmin instead of MYMAX/MYMIN.
Remove scope-limiting braces.
Consistently define literals as floats, except in noise parameters.
Cleanup literals in noise parameters.
Remove unnecessary 'near_cavern' line.
Reduce max spawn y to be consistent with other mapgens.

Mgvalleys: Use shared tunnel / cavern code instead of internal
Caverns first appeared in mgvalleys and were later added to other
mapgens as shared code. Now this shared code can replace mgvalley's
internal cavern code.
Also use shared tunnel code instead of internal code.

Changes to mapgen that will affect existing worlds (mgvalleys is not
stable):

Single lava and water sources not added in tunnels.
Previous caverns are unchanged but an equal number of new ones are
added at a distance from the previous.
From y = -256 to 192 nodes below, where the caverns taper at their
upper limit, they will have a slightly different shape as the taper
is now linear.

Biome API / dungeons: Add biome-defined dungeon nodes
Add new biome fields 'node_dungeon', 'node_dungeon_alt', 'node_dungeon_stair'.
If 'node_dungeon' is not defined dungeons fall back to classic behaviour.

Remove messy and imprecise dungeon material code from 'generateBiomes()'.
Code deciding dungeon materials is now in 'generateDungeons()' and uses the
biome at mapchunk centre for more precision.

Remove hardcoded 'MG_STONE' types as long intended.

Biome API / cavegen: Add definable cave liquid for a biome (#7192)
Add 'node_cave_liquid' as a new field in biome registration.
If field is absent cave liquids fall back to classic behaviour.

Fix many issues reported by clang-tidy (#7189)
* Fix many issues reported by clang-tidy

We have many issues in code related to some performance to float <-> double.
Clang-tidy reported it in performance-type-promotion-in-math-fn

I fixed many of them. It's not ready for a promote to blocking

Also fix some value which should be const-ref
