Fix how the list of linker flags `Z3_DEPENDENT_EXTRA_CXX_LINK_FLAGS`

Browse source 
is applied to targets. The ``LINK_FLAGS`` property of a target is
a string and not a list and so if ``Z3_DEPENDENT_EXTRA_CXX_LINK_FLAGS``
contained more than one flag the linker line would end up being
``-flag1;flag2;flag3;...`` which would not work. Now we use a new
function ``z3_append_linker_flag_list_to_target()`` to iterate through
the list and update the ``LINK_FLAGS`` property of the specified target
correctly.
