CMake: support a custom export group (#970)

Browse Source 
When Pybind11 is used via `add_subdirectory`, when targets are installed
from the parent project, CMake wants all of the dependencies built by
the project in the same export set. Projects may now set
`PYBIND11_EXPORT_NAME` to have Pybind11 put it targets into the
project's export set. If so, do not install Pybind11's export file.
