[binder] Fix WireReaderImpl bugs & races (#27303)

There was a bug found by the fuzzer where we might access wire_writer_ before
finishing SETUP_TRANSPORT (and thus constructing wire_writer_). This PR
fixes such issue by making sure that we won't proceed with any requests
until the connection is fully established.

Since binder transactions may be coming from multiple different threads,
this PRs guard some of the WireReaderImpl's member with a mutex to make
sure there's no races between threads.
