kconfig: lto: Disable when data relocation is enabled

Browse source 
As per issue #69730, building arch.shared_interrupt.lto and
kernel.common.lto for mimxrt685_evk or mimxrt595_evk/mimxrt595s/cm33 is
currently broken due to their usage of CONFIG_CODE_DATA_RELOCATION.

This commit disables LTO when CODE_DATA_RELOCATION is enabled, allowing
PRs with changes in the kernel code to pass the CI check.

On the down side, builds affected by this change produce a new warning:

> warning: LTO (defined at Kconfig.zephyr:430) was assigned the value
> 'y' but got the value 'n'. Check these unsatisfied dependencies:
> (!CODE_DATA_RELOCATION) (=n)
