Implement EncodedBuffer that strip pii based on given privacy request. The reason to implement another buffer is the length-delimited field's size could change when its submessage gets stripped. It also intends to keep the orignal data around for other requests to consume it. In addition, the section implementation has adapted EncodedBuffer so write out to each request's fd could be request-specific. The next step is allow requests to set its privacy spec. Notice the current design set the privacy spec of dropbox to AUTOMATIC, this behavior might change in the future. Bug: 64687253 Test: unit tests are writtern, see README.md for how to run unit tests.
