Fixes #1903
I am not sure if it is good to mutate in onHeaderValue.

But I found it should be the most optimal place to do it.
Trans-code the header value in other place would result in heavy boating code.
For example, it would duplicate the logic if modify in parseHeaders.

undici/lib/core/util.js

Lines 212 to 235 in 7827031

function parseHeaders (headers, obj = {}) {
for (let i = 0; i < headers.length; i += 2) {
const key = headers[i].toString().toLowerCase()
let val = obj[key]
if (!val) {
if (Array.isArray(headers[i + 1])) {
obj[key] = headers[i + 1]
} else {
obj[key] = headers[i + 1].toString()
}
} else {
if (!Array.isArray(val)) {
val = [val]
obj[key] = val
}
val.push(headers[i + 1].toString())
}
}
return obj
}
function parseRawHeaders (headers) {
return headers.map(header => header.toString())
}

You can't process headers in onHeaderValue as they might be incomplete. It needs to be done in onHeadersComplete

Thanks for the helps.
I didn't do it in lib/core/util.js in first place because the code is neat and tidy.
