CXXCBC-639: Allow to build both static and shared libraries

To avoid issues with generation of cmake helper scripts the following
changes has been made:

* interface libraries that are used to carry compiler options and flags
  are declared as IMPORTED to avoid unnecessary INTERFACE_LINK
  dependencies for the static library

* jsonsl, asio and couchbase_backtrace libraries are not linked as a
  targets, but rather as a object files directly. This is also done to
  avoid announcing them as a transitive dependencies. All these
  libraries are hidden and never exposed.

* for other third-party dependencies do not disable install tasks, which
  generate export files

This patch also removes some unused cmake files (of crypto, sasl and
operations/management directories).

Fixes #701
