Ben McClelland 29256f0ab5 feat: add optional data-integrity ETag mode for posix/scoutfs ...

Introduce an opt-in mode that derives ETags from checksums instead of relying on
MD5 assumptions, aligning with AWS-compatible scenarios where ETag should be
treated as an opaque identifier rather than a content-MD5 signal.

This can significantly reduce CPU load on the server to disable MD5 checksums
when we are already validating data with other checksums.

This change adds --data-integrity-etag and VGW_DATA_INTEGRITY_ETAG support for
both posix and scoutfs backends. In this mode, PUT object ETags, multipart part
ETags, and completed multipart object ETags are checksum-derived.
