Add run-webkit-tests support and generate baselines for win8 and win10.

Add run-webkit-tests support and generate baselines for win8 and win10.

This changes the following:
* win10 is now the primary win port version.
* win7 baselines are placed in win7/ instead of win/
* Baseline directory search path is now xp -> win7 -> win8 -> win

are we supporting both 32-bit and 64-bit win8 versions? If so, do we need
different variants elsewhere?
