[Minor] CMake: Add ENABLE_LTO option
* The `CMAKE_BUILD_TYPE=None` option is commonly used to respect the
user's optimization flags. Users may be interested in enabling LTO
anyway in that case. Implement this the Debian build.
* Remove typo, the value is called RelWithDebInfo. Enable LTO for this
by default.
