[PATCH 3/4] sandbox: move CONFIG_ASAN to architecture Kconfig

[Ahmad Fatoum]

KASAN is the bare-metal AddressSanitizer, which we currently only
support on ARM. The hosted variant ASAN will only be supported for
sandbox, so it makes sense to move it out of common/Kconfig.debug
into the sandbox-specific Kconfig.debug.
