Move `Library.runtime` to be a pointer, move the related `LibraryRuntime` struct to `BKE_library.hh`. Similar to e.g. Mesh.runtime, that pointer is expected to always be valid, and is allocated at readtime or when creating a new Library ID. Related smaller changes: * Write code now uses standard ID writing codepath for Library IDs too. * Runtime pointer is reset to nullptr before writing. * Looking up a library by its absolute path is now handled through a dedicated utils, `search_filepath_abs`, instead of using `BLI_findstring`.
