Modify SincResampler to build in webrtc.

This is the first in a series of CLs to bring arbitrary resampling to webrtc.

* Replace Chromium-specific helpers with their respective webrtc versions.
* Add a second constructor to permit runtime selection of block_size.
* Add stringize_macros to system_wrappers.
