Add new hardware and software metrics (#11062)

* Add new hardware and software metrics

* Move sysinfo tests into `mod tests`

* Correct a typo in a comment

* Remove unnecessary `nix` dependency

* Fix the version tests

* Add a `--disable-hardware-benchmarks` CLI argument

* Disable hardware benchmarks in the integration tests

* Remove unused import

* Fix benchmarks compilation

* Move code to a new `sc-sysinfo` crate

* Correct `impl_version` comment

* Move `--disable-hardware-benchmarks` to the chain-specific bin crate

* Move printing out of hardware bench results to `sc-sysinfo`

* Move hardware benchmarks to a separate messages; trigger them manually

* Rename some of the fields in the `HwBench` struct

* Revert changes to the telemetry crate; manually send hwbench messages

* Move sysinfo logs into the sysinfo crate

* Move the `TARGET_OS_*` constants into the sysinfo crate

* Minor cleanups

* Move the `HwBench` struct to the sysinfo crate

* Derive `Clone` for `HwBench`

* Fix broken telemetry connection notification stream

* Prevent the telemetry connection notifiers from leaking if they're disconnected

* Turn the telemetry notification failure log into a debug log

* Rename `--disable-hardware-benchmarks` to `--no-hardware-benchmarks`
