Define CMake components to allow docs to be installed separately (#4276)

Browse Source 
Define two components, core and doc, which can be installed separately.
This facilitates packagers who want to package docs in a separate
package.

After this change it's possible to install only core files with:

     cmake --install build --component core

And only install documentation with:

     cmake --install build --component doc

When no component is specified, the behaviour is unchanged, i.e. if
documentation was built, it will be installed.
