Simplify the Tools and Debug facilities menu entries:

 - each config file no longer have to define their own 'menuconfig foo - if FOO - endif' gym
 - each build script no longer has to say wether they are enabled
 - generation of the 'menuconfig' entries for the Tools and Debug facilities now uses the same code
Some re-ordering of the code to be consistent with the steps ordering (tools, then debug).
