Local GC: GCToOSInterface platform detection

[swgillespie]

The Windows implementation of GCToOSInterface is complete enough to pass tests, but it is not complete - in particular, it does not attempt to do any kind of platform detection or detection of processor capabilities (e.g. 1, 2, 3).

All of the code that is used today to calculate this information exists on the VM side.

@swgillespie Is this going to be fixed for 2.0?

[swgillespie]

Most likely no - it's not needed for correctness of Workstation GC.

[gkhanna79]

In that case, please move it out of 2.0

[swgillespie]

done!
