[CI] Disable runtime logging for benchmarks

[ggwpez]

Changes:

• Disable runtime logging in benchmarks by building with a specific profile

[bkchr]

Could you please give more information on why? I may assume that there are benchmarks that spamming the execution. This sounds more like that they should not spam info or whatever with debug information?

They are not just spamming debug, but also warn and error.
That makes it difficult to see the actual benchmark output from the CLI. Eg:

• polkadot-sdk/polkadot/runtime/parachains/src/paras_inherent/mod.rs

  Line 969 in 1e2a2f0

  log::warn!(target: LOG_TARGET, "ParentBlockRandomness did not provide entropy");

• polkadot-sdk/polkadot/runtime/parachains/src/util.rs

  Line 67 in 22393d5

  log::warn!(

• polkadot-sdk/polkadot/runtime/parachains/src/util.rs

  Line 92 in 22393d5

  log::warn!(

• polkadot-sdk/substrate/frame/staking/src/pallet/impls.rs

  Line 868 in 22393d5

  info,

• polkadot-sdk/substrate/frame/staking/src/pallet/impls.rs

  Line 918 in 22393d5

  log!(info, "generated {} npos targets", all_targets.len());

• polkadot-sdk/substrate/frame/balances/src/lib.rs

  Line 1017 in 68ab943

  log::warn!(

• polkadot-sdk/substrate/frame/beefy-mmr/src/lib.rs

  Line 82 in 22393d5

  log::error!(target: "runtime::beefy", "Failed to convert BEEFY PublicKey to ETH address!");

Maybe i can also intercept the runtime-interface in the benchmarking CLI and redirect the logs there.

Benchmarks should probably just be build like the production binary with on-chain-release-build enabled, which disables any kind of logging.

Oh yea, did not think about this. Thanks!

(Actually going to try it out here)

Okay seems to work. Westend benchmark log file was ~1.25 MB on a recent MR and is now just ~600KB here.
Searching for string Failed to convert BEEFY PublicKey to ETH address also yields no results in the new log.
