Fix a tiny problem in winml.cmake (#23173)

### Description
CMake's
[target_link_libraries](https://cmake.org/cmake/help/latest/command/target_link_libraries.html#id2)
function accepts plain library name(like `re2`) or target name(like
`re2::re2`) or some other kinds of names. "plain library names" are
old-fashioned, for compatibility only. We should use target names.

### Motivation and Context
To make vcpkg work with winml build. See #23158
