For "RT-Thread User Guide":
Take the "RT-Thread Kernel Object Model" sub-section out of
the "Kernel Basics" section and rename it to "Object Management".
Correspondingly, rename the "Kernel Object Management" section
in the "RT-Thread API Guide" to "Object Management".

The original directory structure was too flat and
inconvenient to view.
The directory is now reorganized according to the
first-level chapters, and some sub-chapters are
moved to the second-level directory.
Note: documentation/env is not moved to
documentation/4.tool because there are too many
external places that reference this path,
especially in bsp, so this directory path remains
as it is.
