Resolve macro redefinition warnings when built in Chromium

Chromium defines WIN32_LEAN_AND_MEAN on Windows. Third party library
libtiff also defines it. So we undefine it before compiling libtiff
code for GYP build.

Also, remove _CRT_SECURE_NO_WARNINGS macro since it is redefined in
zlib library as well. Our code no longer needs it.

After fixing the above, re-enable warning flag 4005 which alerts about
"macro redefinition".

For GN build, we disable warning 4005 for compiling libtiff
code before we can figure out another way to do this.
