mac: Introduce libaperitif.dylib
Chrome currently has several .app executables packaged within its bundle
and the the Framework. Each one of these executables statically links
libc++, and in the helpers, a //sandbox target.
Apéritif moves the C++ components of early app initialization into a
shared library, reducing the size of each of the executables. The
executable main file transitions back to being a plain C file rather
than C++ to avoid linking in libc++.
In order to support linking the library to multiple images at different
bundle depths, the linker_driver.py gains the ability to run
install_name_tool as part of the link step.
