feat: redo CV2 and New Modal implementation

[NeloBlivion]

Summary

• View and Modal now only support original components (Button / Select, InputText) - assume behavior from <=2.6.1
• New components are now used in DesignerView and DesignerModal (names not finalised idk)
• Usage is basically the same as rc1, with some differences
  • DesignerView and Container do not support Button, @button, Select and @select directly; use ActionRow instead.
  • Section still supports Button as accessory and the button decorator
  • DesignerModal does not support InputText and Select directly; use Label instead. TextDisplay still works as a top-level component.
  • InputText.description, Select.label and Select.description are removed as they are part of the Label component
• DesignerView can still be used for v1 messages (supporting content and embeds) if you want to migrate to ActionRow for any reason.
• Attempting to add ActionRow to a View will add the row's children instead
• Item has been split into ViewItem and ModalItem
  • InputText and Label now inherit ModalItem
  • All View-based items now inherit ViewItem
  • Select and TextDisplay inherit both ViewItem and ModalItem (even though Select is not a top-level modal item, i believe it still fits)

The provided example code's /modaltest command is all broken.

removing the description kwarg causes additional errors

The above exception was the direct cause of the following exception:
