LoongArch: Add struct loongarch_image_header for kernel 



Define a dedicated image header structure for LoongArch architecture to
standardize kernel loading in bootloaders (primarily for kexec_file).

This header includes critical metadata, such as PE/DOS signature, kernel
entry points, kernel image size and load address offset, etc.
