Several parts of config.json are ineffectual because they use OL2 syntax

[amm-efabless]

There are several things that are incorrect in openlane/SRAM_1024x32/config.json because they are using variables that only work in OL2, hence the harden doesn't have the intended result, namely:

• Power nets don't get connected?
• Routing obstructions are not respected?

I think these are the ones that are wrong, and what they should be changed to:

• VERILOG_POWER_DEFINE should be SYNTH_USE_PG_PINS_DEFINES however I tried running the flow with this change, and it fails with: ERROR: Module `EFSRAM_1024x32_wrapper' referenced in module `SRAM_1024x32' in cell `SRAM_0' does not have a port named 'vpwrp'. -- Without being able to use this, I don't think power nets get connected. Without SYNTH_USE_PG_PINS_DEFINES we instead see: [ERROR]: Can't find vpwrm and vgnd domain. Make sure that both exist in VPWR and VGND. (though the flow still completes).
• ROUTING_OBSTRUCTIONS should be GRT_OBS
• PDN_MACRO_CONNECTIONS should be FP_PDN_MACRO_HOOKS
• VERILOG_DEFINES should be SYNTH_DEFINES
• PL_TARGET_DENSITY_PCT should be PL_TARGET_DENSITY and expressed in 0..1 range.
• RUN_ANTENNA_REPAIR should be GRT_REPAIR_ANTENNAS
• These have no OL1 equivalent?
  • QUIT_ON_PDN_VIOLATIONS
  • RUN_POST_GRT_RESIZER_TIMING
  • RUN_POST_GRT_DESIGN_REPAIR
