Eliminate usage of folly::io::Appender [1/n]

Browse Source 
Summary: When we're writing to a single continuous section of memory (e.g. one created by the `folly::IOBuf` constructor or `folly::IOBuf::create`), we can just use our `BufWriter` from `quic/common/BufUtil.h` instead of using `folly::io::Appender`.
