Remove the deprecated component, components and props options

[pleek91]

Description

Removes the deprecated component and components options and the props argument. Views are added with addView.

Breaking change

// before
createRoute({
  name: 'user',
  path: '/user/[id]',
  component: UserPage,
}, (route) => ({ id: route.params.id }))

// after
createRoute({
  name: 'user',
  path: '/user/[id]',
})
.addView(UserPage, {
  props: (route) => ({ id: route.params.id }),
})

Named views move from components to a name per view.

// before
createRoute({
  name: 'user',
  path: '/user/[id]',
  components: { default: UserPage, sidebar: UserSidebar },
}, {
  default: (route) => ({ id: route.params.id }),
  sidebar: (route) => ({ id: route.params.id }),
})

// after
createRoute({
  name: 'user',
  path: '/user/[id]',
})
.addView(UserPage, {
  props: (route) => ({ id: route.params.id }),
})
.addView(UserSidebar, {
  name: 'sidebar',
  props: (route) => ({ id: route.params.id }),
})

Passing props without a component is no longer supported. A view needs a component to render.

Passing component or components is now an error rather than being ignored, so the compiler points at anything left to migrate.

@stackoverfloweth not going to merge this until after we do the next minor release so we have one version where both are supported for users to use as a migration version.
