1. Follows advice from
https://sol2.readthedocs.io/en/latest/functions.html to use
`set_function` when binding functions.
2. Adds autocomplete support for userdata methods.
3. Simplifies property bindings and improves string handling.
Untangles dependencies by splitting up `engine.{h,cpp}` into 3 files:
1. `primitive_render`
2. `ticks` -- only contains `GetAnimationFrame` for now.
3. `GetWidth2` renamed to `CalculateSpriteTileCenterX` and moved to `levels/dun_tile.hpp`.
We may want to migrate this to 1 file per monster but for now the
migration is as close to the hard-coded version as possible.
Sprites that are used by multiple monsters are only loaded from disk
once.
Fully migrates debug commands to Lua and organizes them into logical
groups.
The CLI `+` syntax now runs Lua, e.g.:
```bash
build/devilutionx '+dev.player.trn.plr("infra")'
```
Chat hotkeys run Lua code if they start with `/lua`, e.g.:
```ini
[NetMsg]
QuickMessage1=/lua message(dev.player.info())
```
