Add support for 64-bit Windows build: base and chrome/app
This is required to support Native Client on 64-bit Windows.
Native Client will use a small 64-bit executable to load NaCl modules on 64-bit Windows. This 64-bit executable will use Chrome code, but some functionality has to be removed to minimize dependencies. This functionality may be enabled later if we decide that it is necessary.
TEST=None
BUG=28176
