flow: every .odb has its .sdc
Every step that writes N.odb writes N.sdc beside it, and every step reads the .sdc beside the .odb it loads. Before synthesis the .sdc is the user's (1_2_yosys.sdc); from 1_synth on, every .odb has its own. This deletes find_sdc_file, which picked an .sdc by name order and gave open_*/gui_* another stage's constraints for a .def or a failed .odb; the second argument of load_design, which named by hand which earlier step's .sdc a script borrowed; the separate orfs_write_sdc and flow_write_sdc calls, now part of orfs_write_db, orfs_copy_db and flow_write_db; and every .sdc rule and prerequisite in the Makefile except the user's, since a step's input .odb comes with its .sdc.
