{module,ecs}: Mach ECS becomes the Mach' module system

Browse source 
This moves the bulk of the ECS code into `src/module`. It also makes
types like `mach.ecs.EntityID` accessible at the top-level `mach.EntityID`
instead.

The motivation of this change is to make the Mach module system a
first-class property of Mach.
