[fix](rest-s3)Set AWS Request Checksum Calculation only if not set, avoid issues on non-S3 storage

AWS SDK for Java v2 uses the system property AwsSystemSetting.AWS_REQUEST_CHECKSUM_CALCULATION to control request payload checksum calculation.
↳

According to the official discussion AWS SDK v2 Discussion #5802
:
↳

By default, the SDK may automatically calculate checksums when required.
↳

For AWS S3, setting the default value "WHEN_REQUIRED" ensures checksums are calculated only when necessary, providing both compatibility and performance benefits.
↳

For non-S3 object storage (such as COS, OSS, OBS), using this default value may cause errors, for example:
↳

aws-chunked encoding is not supported with the specified x-amz-content-sha256 value

because these services do not support AWS-specific chunked encoding or SHA256 checksum.
