f9289f0570 s3: do not promote ?prefix into the object for non-List actions (#11494)
* s3: do not promote ?prefix into the object for non-List actions

authRequestWithAuthType mapped an empty object to the prefix parameter for
every action, so PUT /bucket?versioning&prefix=x authorized as Write:bucket/x.
An object-scoped grant (Write:bucket/*) could then change bucket versioning,
lifecycle, cors, and object-lock configuration, and the promoted object also
made ResolveS3Action report s3:PutObject to attached IAM policies.

* s3: resolve the listing action through the bucket-level object

resolveS3AuthTarget fed the promoted prefix to ResolveS3Action, so a
bucket-level ?uploads request resolved as s3:GetObject on the prefix ARN
in the admin explicit-deny check. Resolve both action and resource
against the object the bucket listing actually scopes.
