render3d: heightgen's plain and SMOOTH variants compiled (61 programs) - a smoothed or noise-only terrain had no height field on Vulkan; run-time defines as pure functions (program_defs.ludic) and manifest_test holds every program the source can ask for, literal or computed, to the manifest

# program_defs.ludic - the defines of every program whose defines are decided at run time, each a pure
# function of what decides it, so tests/manifest_test can ask for every one a run could and hold the
# SPIR-V manifest to them. A new program made with computed defines gets its function here, and a line there.
