token-2022: repair offchain extra metas helper

[buffalojoec]

This stack introduces the necessary repairs to Token2022's extra account metas
helpers in order to solve the issue reported in #6064.

In this particular PR, Token2022's offchain helper is being repaired by first
adding the necessary steps to build an Execute instruction instead of
resolving on a transfer instruction. Then, this introduces a new function that
takes all of the parameters for instruction::transfer_checked(..), to ensure
we are not getting the wrong instruction, as suggested by @joncinque in this PR
comment.

The commit flow is as follows:

1. Repair the original offchain helper, refactor the client and CLI, and
   refactor a transfer hook test in program-2022-test.
2. Add the new helper, deprecating the old one.
3. Add tests for both the deprecated and the new helper.

The guts look great! I think we might be able to make the interface clearer, and otherwise, mostly small points

Thanks for the review @joncinque! If you're not opposed, I think I'll rewrite some of this commit history to shuffle around changes, rather than push up several new ones. Lmk.

Yep, works for me!
