[windows] Fix FindHIP.cmake search for hipconfig. (#583)

Fixes #526. Upstream PR:
ROCm/hip#3789.

* The `find_path` here is looking for the directory containing
`hipconfig`. On Windows, `hipconfig` has the `.exe` suffix.
* The `_EXECUTABLE` code has the option of `.bat` or `exe` suffixes for
`hipcc` and `hipconfig` as both versions exist. CMake's `find_program`
only finds the `.exe` versions, so that code should not append `.bat`
onto the `.exe` (e.g. `hipconfig.exe.bat`).
