Import library for DLL (i.e. rocksdb-shared.lib) requires ARCHIVE DESTINATION. (#4832)

Summary:
`rocksdb-shared.lib` is missing while `rocksdb.lib` and `rocksdb-shared.dll` are installed correctly.
Add `ARCHIVE DESTINATION` to fix this issue.

Refer to CMake doc for more details: [
https://cmake.org/cmake/help/v3.13/command/install.html#installing-targets](https://cmake.org/cmake/help/v3.13/command/install.html#installing-targets)
> ARCHIVE
> Static libraries are treated as ARCHIVE targets, except those marked with the FRAMEWORK property on macOS (see FRAMEWORK below.) For DLL platforms (all Windows-based systems including Cygwin), the DLL import library is treated as an ARCHIVE target.
