Replace deprecated structopt with clap in benchmarks crate

[Yuvraj-cyborg]

Is your feature request related to a problem or challenge?

The benchmarks crate (datafusion-benchmarks) uses structopt for CLI argument parsing, which has been deprecated since 2021. The structopt README explicitly states:

As of clap v3, structopt is now part of clap. Instead of using structopt, use clap directly.

structopt has not been updated in years and adds unnecessary compile-time overhead compared to modern clap derive macros.

This is part of the larger effort to improve benchmark compilation times (#19072 ).

Describe the solution you'd like

Replace structopt with clap (version 4.x) in the benchmarks crate:

Update Cargo.toml:

- structopt = { version = "0.3", default-features = false }
+ clap = { version = "4", features = ["derive"] }

Update all benchmark source files to use clap instead of structopt:

• Change use structopt::StructOpt → use clap::Parser
• Change #[derive(StructOpt)] → #[derive(Parser)]
• Change #[structopt(...)] → #[arg(...)] or #[command(...)]
• Change StructOpt::from_args() → Parser::parse()

Files to update:

• dfbench.rs
• run.rs
• clickbench.rs
• h2o.rs
• run.rs
• cancellation.rs
• sort_tpch.rs
• hj.rs
• nlj.rs
• Any other files using structopt

Describe alternatives you've considered

• Keep using structopt (Not recommended as it's deprecated and unmaintained)

Additional context

• Migration guide from structopt to clap: https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#migrating

Common attribute changes:

structopt	clap
#[structopt(subcommand)]	#[command(subcommand)]
#[structopt(long, short)]	#[arg(long, short)]
#[structopt(about = "...")]	#[command(about = "...")]
#[structopt(name = "...")]	#[command(name = "...")]
#[structopt(default_value = "...")]	#[arg(default_value = "...")]

@alamb @Jefffrey @martin-g

let me know if this improvement is needed !! cuz clap is pretty optimized .

I think it's worth exploring
