Combine linker scripts for single volume and multi-volume ECKD dumpers
to avoid duplicating. Use C preprocessor to define conditional symbols.
Cleanup the generic stage2 linker script(stage2.lds). Since it is still
used for FBA and TAPE dumpers (fba2dump and tape2dump) the .stage2dump.tail
section should be preserved.

Move DF_S390_DUMPER_SIZE_* constants from zdump/df_s390.h to
boot/loaders_layout.h since ccw dumper size depends on the zipl boot
loader layout (to keep it all in one place).

Use a separate linker script eckd2dump_sv.lds for single volume dumper with
compression support.
The new dump tool with zlib compression support now has a size of 8 pages.
Since DASD stand alone dump requires a block size of 4K, we are not
affected by the stage 2 size limitations and can load the dumper to
stage 2 as before. We just need to move the HEAP section for ECKD dumper
in the layout definitions up to 0xb000 address. Also expand the stack by
unused 0x400 bytes.

Use linker script for all bootloaders instead of having the load
addresses of the bootloaders hard-coded in the Makefile. This allows us
to simplify the Makefile and it fixes the dependency tracking for the
bootloaders *0.bin, *1.bin, and *1b.bin.

This allows the reuse of the macro in the next patch. In order to match
the naming scheme rename `STAGE1B_LOAD_ADDR` to `STAGE1B_LOAD_ADDRESS`.

Use C pre-processor for linker script generation and refactor some
constants. This allows the usage of the constants in our "linker
scripts" `*.lds.S` (actually, these are assembler files, so we can
make us of the C pre-processor and its capabilities).
While at it, enforce the described memory layout in the generated
linker script.

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.
