evas_image_main: make the cache->usage count eina_file size

Summary:
The image.data is set to null by evas_common_rgba_image_unload_real.
After this point the cache->usage does not count cache_entry.w and h value when
evas_gl_common_image_free calls evas_cache_image_flush.
So the cache->usage increases just around 300. If the cache->limit is 4194304,
then the cache could have around 1398 items. This would be fine.

But each items hold eina_file, and the cache does not count eina_file size.
If the file size is 326352, then a process could use 456527385 bytes.

So this patch set make the cache->usage count eina_file size.
This would be better option than https://phab.enlightenment.org/D7029
