Treat custom textures with "_arb" suffix as having arbitrary mipmaps

This is adapted from Bighead's code that was posted at
https://forums.dolphin-emu.org/Thread-dolphin-custom-texture-mipmaps?pid=460867#pid460867

In master, custom textures are never treated as having arbitrary mipmaps,
so we need either a change like this or a change that makes us apply the
arbitrary mipmap heuristic even when a custom texture is used.
