v8: remove void* cast in ptr_arg_cmd

This commit removes the addition of a void* cast ptr_arg_cmd. The
motivation of this is that currently the jlh command does not work. For
example:
(lldb) jlh env()->quic_on_socket_ready_function()

With this change the jlh command works as expected:

(lldb) (lldb) jlh env()->quic_on_socket_ready_function()

    #prototype: 0x3d6ba9980501 <AccessorInfo> (const accessor descriptor)
 }

I'm not sure yet how the other commands that use ptr_arg_cmd are
affected but thought I'd bring this up as a WIP incase others are seeing
the same issue.
