Commit ae91aa0adb14(rcu: Remove debugfs tracing) removed the RCU debugfs

Because exp_workdone{0,1,2,3} won't be used anymore since the commit,
it's better to remove code to do with those variables. Remove it.

If new choice values are added with new dependency, and they become

If a symbols has dependency on the preceding symbol, the menu entry
should become the submenu of the preceding one, and displayed with
deeper indentation.
This is done by restructuring the menu tree in menu_finalize().
It is a bit complicated computation, so let's add a test case.

The calculation of 'choice' is a bit complicated part in Kconfig.
The behavior of 'y' choice is intuitive. If choice values are tristate,
the choice can be 'm' where each value can be enabled independently.
Also, if a choice is marked as 'optional', the whole choice can be
invisible.
Test basic
The variable 'PYTHON' allows users to specify a proper executable
name in case the default 'python' does not work. However, this does
not address the case where both Python 2 and Python 3 scripts are
used in one source tree.

If tristate choice values depend on symbols set to 'm', they should be
hidden when the choice containing them is changed from 'm' to 'y'
(i.e. exclusive choice).
This issue was fixed by commit fa64e5f6a35e ("kconfig/symbol.c: handle
choice_values that depend on 'm' symbols").
