[llvm] Move raw_string_ostream back to raw_ostream.cpp (PR #79224)

[Andy Kaylor via llvm-commits]

https://github.com/andykaylor created https://github.com/llvm/llvm-project/pull/79224

The implementation of raw_string_ostream::write_impl() was moved to raw_socket_stream.cpp when the raw_socket_ostream support was separated. This patch moves it back to facilitate disabling socket support in downstream projects.
