Scott Graham c82309f0e5 fuchsia: Implement StartHandler() and ExceptionHandlerServer
StartHandler() binds to the default job's exception port, and launches
the handler process (normally this is crashpad_handler), passing it the
task handle and a handle to the exception port as startup parameters.
This follows the protocol used by crashlogger.

Additionally, implement ExceptionHandlerServer in crashpad_handler,
which contains the exception processing loop. It currently dispatches to
an empty CrashReportExceptionHandler where a report will be written
eventually.
