configs: Add coreboot64-no-spl_defconfig for 64-bit X86 without SPL

Create a new defconfig file called `coreboot64-no-spl_defconfig`,
tailored specifically for 64-bit X86 architecture systems that operate
without the Secondary Program Loader (SPL). This configuration takes its
inspiration from `coreboot64_defconfig`..
