Remove typehint from output protocol
Remove typehint from output protocol

Summary:
Internally at FB we post process some php generated thrift into Hack in
//decl mode, which breaks this typehint since the typehint is for a nonnullable
TProtocol but the value is nullable.

Since we still want to support raw php, lets remove the typehint.

Test Plan: Regenerate affected thrift file, changes are sane
