roadrunner: [🐛 BUG]: Request field ordering is random

No duplicates 🥲.

• I have searched for a similar issue in our bug tracker and didn’t find any solutions.

What happened?

Sending the same HTTP request (multipart/form-data) to Roadrunner is sending randomly ordered parameters to PHP.

It’s causing issues with GraphQL specs validation, like in this bundle - https://github.com/overblog/GraphQLBundle/blob/master/src/Request/UploadParserTrait.php#L68

Version (rr --version)

2023.1.4 / 2023.1.5 / 2023.2.0-beta.3

How to reproduce the issue?

1. Send Request to PHP application:

curl 'http://localhost/' -H 'Accept: application/json' -H 'Content-Type: multipart/form-data; boundary=----BND' \
  --data-raw $'------BND\r\nContent-Disposition: form-data; name="var1"\r\n\r\nfirst\r\n------BND\r\nContent-Disposition: form-data; name="var2"\r\n\r\nsecond\r\n------BND--\r\n'

1. Observe parameters are randomly displaying var1 or var2 as the first parameter in $buffer variable here: https://github.com/roadrunner-php/goridge/blob/4.x/src/StreamRelay.php#L88
