Dont query remote cache but always use bytestream protocol

When using `--experimental_remote_build_event_upload=minimal`, instead of querying remote cache to decide whether convert local path of a file to `bytestream://`, it now always use `bytestream://` for BEP referenced files. Closes #16999. Closes #17025. PiperOrigin-RevId: 502351401 Change-Id: Ic858367ffaf3c2a2c20db88ada85fbbe1d93aae8
