ref-manual: Added 'debug-tweaks' fragmentation.

The image feature 'debug-tweaks' has been fragmented into three
separate areas of functionality that deals with handling empty
passwords and post-installation logging.  I updated the list of
image features appropriately and the description of 'debug-tweaks'
in the EXTRA_IMAGE_FEATURES variable.

Fixes [YOCTO #5344]
