Clarify internals hal functions and files names

The purpose of this commit is to have of a more standard way to
name files and functions used to generate/handle hal api
(generated from hal json configuration file).
It occurred to me that 'hal-controller' was not a good name
because it is harder for people who don't know about
the app-controller to understanded what is the purpose of
these files/functions.

It was renamed to 'internal-hal' because it's about hal
that are all handle/load by hal-manager in opposition of
external-hal that are independant binding/binder that can register
themselves to hal-manager.
