Kconfig: consolidate the "Kernel hacking" menu

Browse Source 
Move the source of lib/Kconfig.debug and arch/$(ARCH)/Kconfig.debug to
the top-level Kconfig.  For two architectures that means moving their
arch-specific symbols in that menu into a new arch Kconfig.debug file,
and for a few more creating a dummy file so that we can include it
unconditionally.

Also move the actual 'Kernel hacking' menu to lib/Kconfig.debug, where
it belongs.

For most platforms, it is firmware or second stage bootloader
that by default specifies the kernel command line options.
However, it might be necessary or advantageous to either override
the default kernel command line or add a few extra options to it.
For such cases, this option allows hardcoding command line options
directly into the kernel.
For that, choose 'Y' here and fill in the extra boot parameters
in CONFIG_CMDLINE.
The built-in options will be concatenated to the default command
line if CMDLINE_FORCE is set to 'N'. Otherwise, the default
command line will be ignored and replaced by the built-in string.
