cmake: omit linking duplicate/unnecessary libs to tests & examples

Browse source 
Before this patch we explicitly linked the full list of libcurl
dependency libs to tests and examples via `CURL_LIBS`. This was
redundant, because test and example code do not directly use these
dependency libs and for indirect use they are implicitly passed
via libcurl as needed. After this patch, tests and examples only link
explicitly to system libs (e.g. socket).

Also bringing it closer to how `./configure` does this.

Borrow the variable name `CURL_NETWORK_AND_TIME_LIBS` from
`./configure`. However, its content is not exactly the same. With cmake
it also holds `pthread`, but doesn't hold AmiSSL.

Closes #17696
