zipl: move loaders layout definitions into separate header

Browse Source 
Move the loaders (stage2/stage3) layout values to
`include/boot/loaders_layout.h` and use the `_AC` macro for the
constants. This allows the reuse of the definitions, e.g. in assembler
files, and later for the creation of linker scripts.
