libchrome: Fix Mac build
The recent uprev attempt missed a couple Mac-specific files.
Adding them now.
Also, there were some other build breaks in Mac files.
Particularly, had to revert the uprev change to the following file
base/message_loop/message_pump_mac.mm because the change relied
on base::mac::CallWithEHFrame() which was implemented in assembly
and didn't compile on 32 bit platform. So, I have removed the
change introduced with https://codereview.chromium.org/1212093002
on Chromium side.
