Instruction weights and custom sequence about riscv-dv HOT 3 CLOSED

Thanks

For the weights, you can add distribution constraints in below class (right now there's no knob to control the weights)

For custom sequence, you can find some examples here:
https://github.com/google/riscv-dv/blob/master/src/riscv_directed_instr_lib.sv
https://github.com/google/riscv-dv/blob/master/src/riscv_load_store_instr_lib.sv

Here's how the custom sequence is mixed with the random sequence
