Reduces memory usage on the server, especially with many user and/or large viewing distances.
Currently disabled on the client due to known data races on a block's data.
Large structures which are generated in on_generated callbacks
independently by Lua cannot influence decoration placement. This
change enables such a callback to assume responsibility for generating
decorations itself, presumably after structures are placed, by
disabling decorations in mg_flags and executing
core.generate_decorations.

These changes were initially made to improve performance. However,
on modern hardware, these changes turned out to make no difference.
This commit unifies the calculations in 'draw' and 'getDimension' and
adds comments to make it more understandable.
* Feature: Use the builtin profiler to automatically make zones for mod callback functions.
* Doc: Basic doc for builtin profiler, and better `/profiler` chatcommand help.
* Fix: `register_functions` (table of callback register function names), and `entity_instrumentation` is no longer outdated.
* Fix: Builtin profiler output is no longer printed to debug.txt or to file in world with translation escapes.
* Fix: Entity callback name generation used `obj_def.label` (normally non-existing field), now it uses the entity name.
* Small code improvements, like use of new `Settings.get_bool` with default.
A few functions tried to dereference a ServerEnvironment nullptr by
calling 'getEnv()'. This change makes use of a macro where possible.
This also cleans up incorrect macro uses, with no functional difference.
This change prevents issues arising from partial generation of MapChunks, which are liable to be regenerated completely when ungenerated MapBlocks within are encountered.
