Re: [webrtc-pc] `getCapabilities` seems to leak hardware capabilities w/o a permission (#2460)

I've created a [document](https://docs.google.com/document/d/1XWutvNNXu3iXA-6ZpYpwY7KRwh87_6s97WBNIOs5-Kg/) which describes what is returned in `getCapabilities()` versus what is in the SDP returned by `createOffer`, `createAnswer`, etc.  AFAICT, the only thing that is in `getCapabilities` but not in the SDP is information on the supported scalability modes. Since hardware rarely provides additional support for encoding of scalability modes the additional information doesn't help with fingerprinting.
