This cl removes a lot of unused functionality in SystemInfo and reduces dependencies.
There's duplicate functionality in this class and WebRTC's CpuInfo class, so I'm consolidating the two implementations.
The CpuInfo interface will still exist since it's being used from Chrome to initialize the core count before the sandbox is engaged.
With this change, the SystemInfo class will get the benefit too of this initialization.

Mostly this consists of marking functions with override when
applicable, and moving function bodies from .h to .cc files.
Not inlining virtual functions with simple bodies such as
{ return false; }
strikes me as probably losing more in readability than we gain in
binary size and compilation time, but I guess it's just like any other
case where enabling a generally good warning forces us to write
slightly worse code in a couple of places.
