[Bug][move-compiler-v2] constants should not be able to refer to other constants

[brmataptos]

🐛 Bug

See the test outputs:

• third_party/move/move-compiler/tests/move_check/typing/constant_allowed_but_not_supported.exp
• third_party/move/move-compiler-v2/tests/checking/typing/constant_allowed_but_not_supported.exp
  V2 does not complain about the use of const names in other consts.

In PR #14578 I'm adding a new test case

• third_party/move/move-compiler/tests/move_check/typing/recursive_constant.exp
• third_party/move/move-compiler-v2/tests/checking/typing/recursive_constant.exp
  which shows totally unexpected code generated by V2 in the case of recursive constants.

This needs to be fixed.

Instead of not allowing it, I am wondering whether we could check recursive use of other constants?
