feature: Enabling debug variables reader in ocloc

This allows for using debug variables in ocloc with
a few by-design limitations :
* debug var needs to be prefixed with NEO_OCLOC_
(when setting-up at runtime as environment variable
or using .config file)
* debug var needs to be tagged with S_OCLOC scope
(at compile time, in debug_variable .inl files)
