[CX_CLEANUP] - Diverge the Quorum Vote Task

[shenkeyao]

Closes #3172. Currently a draft, because it's based on https://github.com/EspressoSystems/HotShot/pull/3156. Will rebase after that PR is merged.

This PR:

• Adds the ValidatedState dependency to the quorum vote task.
• Refactors the update_state_and_vote_if_able function:
  • Adds the dependency-task-related logic to the vote task.
  • Only uses it in non-dependency tasks.
  • Updates quorum vote task tests.
    • Adds the ValidatedStateValidted event to the inputs.
    • Fixes incorrect view index.
    • Adds a test for mismatched inputs.
• Misc:
  • Combines test_helpers.rs and task_helpers.rs into helpers.rs.
  • Renames create_fake_view_with_leaf_* functions to build_fake_view_with_leaf_* to be consistent with other names.
  • Renames disperse_share to vid_share, and VID disperse to VID share.

This PR does not:

Change other tasks other than the vote task.
