[PATCH RFC] init/Kconfig: enable -O3 for all arches

From: Oleksandr Natalenko
Date: Tue Dec 10 2019 - 09:57:08 EST

Building a kernel with -O3 may help in hunting bugs like [1] and thus
using this switch should not be restricted to one specific arch only.

Thus lets expose it. If for some reasone we have to hide it, lets hide
it under EXPERT.

The commit is made against next-20191210 tag.
