Split more targets from chrome.gyp to add support for building Native Client for 64-bit Windows.

This CL is required for supporting Native Client on 64-bit Windows. On Win64 we will use a 64-bit executable to load NaCl modules. Since we have only one version of Chrome on Windows, this executable has to be built together with 32-bit Chrome binaries.
For the targets that are required for both 32-bit and 64-bit builds, this CL moves the shared parts of the target definitions into target-specific gypi files (such as base.gypi). New 64-bit only targets are added. Since we would like to port as few code as possible at this point, some 64-bit targets include less source files or less dependencies than the original 32-bit targets. These targets will have nacl_win64 in their name - to emphasize that they should be used for NaCl only. Some 64-bit targets are identical to the 32-bit targets in everything except for the target platform - these will have only win64 in their name.
