Add a bundle no_UTP_lattice_syntax to switch off UTP lattice syntax

[RandallYe]

In my mechanisation, I don't need lattice syntax from UTP and would use the lattice syntax from Isabelle HOL. For this reason, I have added a bundle no_UTP_lattice_syntax to switch off UTP lattice syntax.

By the way, I change the name utp_lattice_syntax to UTP_lattice_syntax to make its name consistent with other bundle names in UTP, like UTP_Logic_Syntax.

After this update, I have the following commands at the beginning of my theory:

unbundle UTP_Syntax
(* Switch off lattice syntax from UTP )
unbundle no_UTP_lattice_syntax
( Switch on lattice syntax from HOL *)
unbundle lattice_syntax

@simondfoster do you think this change can be adopted by UTP? I think it might be useful in the future for other users. If not, I probably consider leaving this change locally in my theories. I need to make a decision about which way I will use it in my code because I need to hardcode the links to the theories in a paper.

Any questions, please do let me know. Thanks.
