Enable win64 stub library generation.
Previously, /machine:X86 was the hardcoded lib option.
This patch enables /machine:X64, if the file type parameter is 'windows_lib_x64'. To unblock media <-> ffmpeg win64 linking, this patch along with a separate patch to ffmpeg.gyp will be necessary.

BUG=172938, 166496
TEST=win_rel try bot (win32). Private with additional fix to use 'windows_lib_x64' for win64 in ffmpeg.gyp eliminates media<->ffmpeg link errors in win64. Unittests.
