Some tweaks for the arm64 EFI header and the zboot version, to add the annotation that informs the loader that the code regions may be mapped with BTI enforcement enabled. As a related cleanup, add the combined codesize (text+rodata+inittext) to the arm64 Image header, so the EFI zboot loader can grab it from the image after decompressing it.
