<chromium> MSVC: Fix build issues when using std::numeric_limits::max

On Windows the core library did not compile because of
a cascading include of base/time/time.h which includes
windows.h. This in turn results in min and max macros
being defined, which for some obscure reason msvc confuses
when std::numeric_limits::max is used.
Undef these unneeded macros to fix the build.
