[release-branch.go1.21] net/http: revert "support streaming POST content in wasm"
CL 458395 added support for streaming POST content in Wasm.
Unfortunately, this breaks requests to servers that only support HTTP/1.1.
Revert the change until a suitable fallback or opt-in strategy can be decided.
For #61889.
Fixes #62328.
