arch: x86: remove arch specific dependencies from DYNAMIC_BOOTARGS

CONFIG_DYNAMIC_BOOTARGS currently depends on CONFIG_MULTIBOOT_INFO
and CONFIG_BUILD_OUTPUT_EFI which are x86 specific.

This change removes those dependencies so that another architecture
can use CONFIG_DYNAMIC_BOOTARGS without the x86 specifc features.
