Add SM_CXSIZEFRAME and SM_CXPADDEDBORDER metrics to get window border size.

Vista added the SM_CXPADDEDBORDER system metric which needs to be included
in the border size. The previous code happened to work with 32-bit Chrome
because Windows added the padding into SM_CXSIZEFRAME (and set the padding to 0)
for backwards compatibility, but with 64-bit that changed.
GetSystemMetrics(SM_CXPADDEDBORDER) should always return 0 on XP.
