gpio_signal_buffering rtl decaps 

+ add sky130_ef_sc_hd__decap_12 decaps in the rtl of gpio_signal_buffering
+ add sky130_ef_sc_hd__decap_12 stub file for openlane; there is no
yosys-parseable verilog model for sky130_ef_sc_hd__decap_12
~ change config of gpio_signal_buffering* to add sky130_ef_sc_hd__decap_12
~ regenerate the gl netlist based on the above changes
