CMakeExpandImportedTargets: Document as deprecated

The module is not needed anymore for try_compile or try_run.  It cannot
be used with CMP0022 NEW behavior due to generator expressions in
INTERFACE_LINK_LIBRARIES, so document it as deprecated.  Whatever
problems other than try_compile and try_run anyone tried to solve with
this module will have to be addressed another way.

# Deprecated. Do not use.
#
# This module was once needed to expand imported targets to the underlying
# libraries they reference on disk for use with the :command:`try_compile`
# and :command:`try_run` commands. These commands now support imported
# libraries in their ``LINK_LIBRARIES`` options (since CMake 2.8.11
# for :command:`try_compile` and since CMake 3.2 for :command:`try_run`).
#
# This module does not support the policy :policy:`CMP0022` ``NEW``
# behavior or use of the :prop_tgt:`INTERFACE_LINK_LIBRARIES` property
# because :manual:`generator expressions <cmake-generator-expressions(7)>`
# cannot be evaluated during configuration.
