feat: enhance benchmarking experience via command pop benchmark parachain

[chungquantin]

Current state of benchmarking experience, it takes manage steps to build > generate weights.

cargo build --profile=production --features runtime-benchmarks

./target/production/node-template benchmark pallet \
    --chain dev \
    --execution=wasm \
    --wasm-execution=compiled \
    --pallet "*" \
    --extrinsic "*" \
    --steps 50 \
    --repeat 20 \
    --output pallets/all-weight.rs

pop-cli can definitely simplify this process with one command pop benchmark parachain
