Subject: capture/replay: implement infrastructure for capture (#4372)

* Define api call ID for each being captured methods

* Add parameter encoder interface

* Add outputStream and capture manager

Add infrastructure for output stream
    This is the interface to record the method and parameter, and also
    provide functionality to write all the serialized data into file.

Add capture manager:
    Capture manager is associated to global session object, it will
    provide the functionality to actual record all the APIs.

Implement some of parameter encoder functions.

* Fix some Windows & cmake build error

* remove unused headers
