Fix use-after-free issue for dexfile
When we open a dex file, class linker will save dex file address in
dex_caches_. Then when GC occurs, the dex file will be freed in
art::DexFile_closeDexFile, but dex file address is still in dex_caches_.
When some tries to iterate over dex_caches_, HWASAN complains.
Therefore remove the dexfile in dex_caches_ when we delete the dex file.
