Remove 15 BITMAPS enum values that have no registered image data
in bitmap_info.cpp and no remaining code references. These were
placeholders for constraint types that either never got SVG artwork
or used different naming than the generated bitmaps.
Removed: constraint_net_antenna, constraint_short_circuit,
constraint_unrouted, constraint_allow_fillet_outside_zone_outline,
constraint_silk_to_silk_clearance, constraint_minimum_acute_angle,
constraint_matched_length_all_traces_in_group,
constraint_absolute_length, constraint_parallel_limit,
constraint_daisy_chain_stub, constraint_daisy_chain_stub_2,
constraint_corner_style, constraint_smd_corner,
constraint_smd_entry, constraint_smd_to_plane_plus
