Evaluate WPCS VIP issues

As part of [WPCS's reorganisation of labels](https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/1454), the `Component: VIP` is being removed, since WPCS `master` no longer contains the VIP category of sniffs.

The following Issues were still open at the time the label was removed, so these need checking to see if they still apply to any code that we now have in VIPCS:

- [x] ~https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/1379~
- [x] ~https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/662~
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/661 (Applicable to WPCS)
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/461 (Applicable to WPCS)
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/462 (Possibly applicable to WPCS)
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/74 (Possibly applicable to WPCS)
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/91 (Valid for VIPCS, but not easily sniffable)
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/80 (Valid for VIPCS, but not easily sniffable)
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/295 (Likely valid for VIPCS)
- [ ] https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards/issues/475 (Likely valid for VIPCS)

Bắt đầu bằng việc đọc issue 1454 về việc tái tổ chức WPCS được liên kết, sau đó xem xét mười issue đang mở được liệt kê ở đây, đặc biệt là 661, 461, 462, 74, 91, 80, 295 và 475. So sánh từng issue với phạm vi hiện tại của VIPCS và WPCS; hoàn tất nghĩa là ghi lại liệu issue đó còn áp dụng hay không và xác định mọi việc cần theo dõi tiếp.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
