API documentation: Re-organize chapters and sections 

* Split the very long 'Base Interface' section into smaller sections.
* Split the 'Core API' chapter into two chapters.
* Remove single enumeration values from `@order` fields since they have no
  effect.

* This section describes the most important public high-level API
* functions of FreeType~2.
* Macros to test the most important font properties.
*
* It is recommended to use these high-level macros instead of directly
* testing the corresponding flags, which are scattered over various
* structures.
