feat(presign): support presign head method for s3 and oss

[ZhiHanZ]

I hereby agree to the terms of the CLA available at: https://databend.rs/dev/policies/cla/

Summary

This pull request adds support for generating pre-signed URLs for the HEAD method on Amazon S3 and Aliyun OSS (Object Storage Service) objects.

This allows clients to perform presign head operation on s3 or oss, as an example:

use anyhow::Result;
use futures::io;
use opendal::services::memory;
use opendal::Operator;
use time::Duration;
# use opendal::Scheme;

#[tokio::main]
async fn main() -> Result<()> {
    let op = Operator::from_env(Scheme::Memory)?;
    let signed_req = op.object("test").presign_stat(Duration::hours(1))?;
    let req = http::Request::builder()
        .method(signed_req.method())
        .uri(signed_logreq.uri())
        .body(())?;

    Ok(())
}

This pull request has passed all the necessary checks and tests, including static analysis with cargo check, linting with cargo clippy, unit and integration tests with cargo test, and benchmarking with cargo bench.
