kconfig: Don't USE_DT_CODE_PARTITION if there isn't one
Previously, if there was no `zephyr,code-partition` chosen DT node, then enabling CONFIG_USE_DT_CODE_PARTITION would make all of flash available to the linker, with no immediate indication of that to the user. To avoid this discrepancy, make the USE_DT_CODE_PARTITION Kconfig symbol depend on that chosen node being present. For the sake of verbosity, add a dedicated symbol to describe this: HAS_DT_CODE_PARTITION. An additional benefit is that certain platforms or applications can now use `select USE_DT_CODE_PARTITION` to signal `zephyr,code-partition` as a hard requirement, by failing the build whenever the node is missing.

When enabled, the application will be linked into the flash partition

When this is disabled, the flash load offset and size can be set manually
