[FIX] doc: complete tale about two profilers

This section of log mentionned two profilers making think they were the
same.

The odoo/tools/misc.py `profile` logs a method calls inside a file that
can be used to generate a graph of method calls.

The odoo/tools/profiler.py `profile` logs a method lines calls, queries
and time spend inside the log.
