Rewrite base::Bind to base::BindOnce with base_bind_rewriters in //chrome/browser/chromeos/arc

This is a generated CL by a clang refactoring tool at //tools/clang/base_bind_rewriters.
It rewrites base::Bind to base::BindOnce where the resulting Callback is converted to
OnceCallback immediately.
E.g.:
  base::PostTask(FROM_HERE, base::Bind(&Foo));
is rewritten to:
  base::PostTask(FROM_HERE, base::BindOnce(&Foo));

In terms of the behavior change after the rewrite, the OnceCallback
implementation moves out the bound argument to the target function, unlike
Callback.
