When a new variant is created, it needs to have a path to its SPD binary
defined. Currently, this is done by setting SPD_SOURCES to a placeholder
SPD file, which just contains zero bytes.
To remove the need for a placeholder file, automatically generate a
single-byte spd.bin in lib/Makefile.inc when SPD_SOURCES is set to the
marker value 'placeholder'.

When a new variant is created, its SPD_SOURCES contains a placeholder
file, to avoid a build failure due to SPD_SOURCES being empty. Currently
these placeholder files live with the rest of the SPD files in soc and
mainboard directories, e.g.
src/soc/intel/alderlake/spd/placeholder.spd.hex

Use the new unified version of the spd_gen tool to generate all LP4x and
DDR4 SPDs, storing them in a new spd/ directory. Storing them in a
common location allows platforms with the same SPD requirements to share
SPD files, reducing duplication compared to storing SPDs in soc/ and
mainboard/ directories.
For each memory technology there are multiple sets of SPDs. Each set
corresponds to a set of platforms with different SPD requirements, e.g.
due to different memory training code expectations. A manifest file
(platforms_manifest.generated.txt) lists the platform -> set mappings.
Commands used to generate SPDs:
cp util/spd_tools/lp4x/global_lp4x_mem_parts.json.txt \
spd/lp4x/memory_parts.json
cp util/spd_tools/ddr4/global_ddr4_mem_parts.json.txt \
