LOG: [libunwind][cmake] Create `LIBUNWIND_INSTALL_INCLUDE_DIR` CACHE PATH

This is created on analogy with the other CACHE PATHs in this package,
and other `*_INSTALL_INCLUDE_DIR` in other packages.

The branching is adjusted to deduplicate some existing code, and
likewise avoid having to define this new variable more than once.

This will be used for D99484.
