This has the triple bonus effect of a) making a lot of code easier to read, b) reducing Server::getInstance() usages, and c) removing a whole bunch of Server dependencies.
The network and block namespaces are untouched by this commit due to potential for merge conflicts. These should be dealt with separately on master.
Once upon a time, these userland functions were faster than calling builtins, but not anymore. According to my test the Math functions are twice slower in PHP 7.2 with typehints and 50% slower without typehints.
Inlining is slightly faster than using builtins, but the difference is very small - not worth making the code look any more ugly than it does already.
This allows the removal of lots of ugly code, and also exposes lots of similarities with how this update type was handled. This can be further improved in the future to more generically handle cases.
I realized in the process of changing this, that it might actually be simpler to treat to treat scheduled updates and neighbour updates as one and the same. They use the same mechanism for being saved on chunks (TileTicks),
and doing that would make updating only require one queue instead of two.

this is not technically correct behaviour, but this preserves the current behaviour.
These changes produce about 3x performance improvements. Some numbers
from my machine (i7-7700k @ 4.5GHz) with TNT:
- before changes: 35ms
- after changes: 11ms
in powersave mode (0.9GHz):
- before changes: 170ms
- after changes: 60ms
- All entity and tile constructors now require a \pocketmine\level\Level instead of a \pocketmine\level\format\Chunk.
- Chunk->getProvider() and Chunk->setProvider() have been removed.
- Chunk::__construct() has had the $provider parameter removed.
- Chunk->unload() has had the unused $save parameter removed.
- ChunkEvents now take a Level parameter instead of going through the Chunk
