Normalizes a request body into the string that gets recorded on the span.
OTel drops attribute values that are not primitives (or arrays of them),
so any body left as an object (FormData, URLSearchParams, Blob,
ArrayBuffer, ...) was silently lost.
Returns undefined when there is nothing recordable: no body, or a stream
that has to be captured up front (see installFetchRequestBodyCapture).
