[CMake] Option to control whether shared/static library is installed
Currently it's only possible to control whether shared or static library
build of libc++, libc++abi and libunwind is enabled or disabled and
whether to install everything we've built or not. However, it'd be
useful to have more fine grained control, e.g. when static libraries are
merged together into libc++.a we don't need to install libc++abi.a and
libunwind.a. This change adds this option.
