Move BOOTLOADER_MCUBOOT configuration from boards/espressif/<BOARD>/Kconfig.sysbuild to soc/espressif/Kconfig.sysbuild so it applies generally to every board with Espressif's SoC when building a project using sysbuild. Signed-off-by: Almir Okato <[email protected]>

Use sysbuild to build MCUboot Espressif Port as an external project.
The current sysbuild usage for Espressif should not be affected, so the regular
west build <BOARD> <SAMPLE> --sysbuildstill builds Zephyr Port. In order to build Espressif Port, the KconfigCONFIG_BOOTLOADER_MCUBOOT_ESPRESSIFneeds to be enabled on the sysbuild menuconfig, or it can be passed as sysbuild domain variable in the command line--sysbuild -DSB_CONFIG_BOOTLOADER_MCUBOOT_ESPRESSIF=y.Kconfigs for Espressif's
Kconfig.sysbuildwere added to match MCUboot Espressif Port configuration, so they are partially similar to the regular Zephyr Port, but notice it's a different MCUboot Port.CONFIG_MCUBOOT_ESPRESSIFindicates that the current build is MCUboot Espressif Port image. Defined in Espressif Port from MCUboot repository.(SB_)CONFIG_BOOTLOADER_MCUBOOT_ESPRESSIFindicates to Espressif's sysbuild cmake that it needs to build the MCUboot Espressif Port bootloader and that it needs to set the main image as a MCUboot compatible image, similar as Zephyr already does with the CONFIG_BOOTLOADER_MCUBOOT for setting Zephyr Port and MCUboot compatibility when building with sysbuild.How to build and test:
