tracehook: CONFIG_HAVE_ARCH_TRACEHOOK
This adds the generic HAVE_ARCH_TRACEHOOK kconfig item. Each arch should
add to some Kconfig file:
select HAVE_ARCH_TRACEHOOK
if the arch code uses all the latest hooks to enable newfangled tracing
and debugging code. The comment in arch/Kconfig lists all the
prerequisite arch support. When all these are available, setting
HAVE_ARCH_TRACEHOOK will allow enabling any new features that depend on
the modern arch interfaces.
