Justin Zaun 9288889e20 gowin: add hardware latch support (DL/DLN/DLC/DLP variants) ...

Add simulation models, techmap, and dfflegalize rules for Gowin
DL-series latch primitives. Latches use the same physical BEL as
DFFs with REGMODE set to LATCH. All 12 variants are supported:
DL, DLE, DLN, DLNE, DLC, DLCE, DLNC, DLNCE, DLP, DLPE, DLNP, DLNPE.
