Describe the technical details

What is currently done? (Provide issue link if applicable)

1. For set_clock_pin, use the auto-generated SDC from extractor
2. Do not use FCLK path for routing CC pin to fabric

• Existing solution had been proven working on flop design simulation
• But found a new path where we can route the CC pin via gearbox RX_clock_IO feature
• This new path save FCLK resource(s)
• But need to re-test flop design

Coverage failed because currently we do not have unit test that cover Compiler code to compile a project

Testing done:

• Port this PR (together with Various enhancement yosys_verific_rs#660) to latest NS Raptor
• Run test/batch, test/batch_gen2. test/batch_gen3 and /up5bit_counter_dual_clock_bitstream, all GJCs project
