Move the HAVE_ARCH_* config options from src/arch/x86 to src/.

The options that keep track of whether there are arch versions of the standard
string functions shouldn't be in the arch/x86 directory since they apply to
all architectures. Move them into the higher level, shared Kconfig defaulting
to off. Then, in each applicable arch (currently all of them) they can be
selected to on.
