refactor!: port vue-portal to teleport or extension system

[JammingBen]

Breaking changes for portal und portal-target usages

• Global $wormhole on vue instance has been removed
• PortalTarget component has been removed
• app.files.sidebar.file.details.table portal target has been removed. Register an extension on the app.files.sidebar.file-details.table extension point instead.
• app.files.sidebar.space.details.table portal target has been removed. Register an extension to the app.files.sidebar.space-details.table extension point instead.
• app.files.sidebar.sharing.shared-with.top portal target has been removed. Register an extension on the app.files.sidebar.shares-panel.shared-with.top extension point instead.
• app.files.sidebar.sharing.shared-with.bottom portal target has been removed. Register an extension on the app.files.sidebar.shares-panel.shared-with.bottom extension point instead.
• app.runtime.header.left portal target has been removed. Register an extension on the app.runtime.header.left extension point instead.
• app.runtime.header.right portal target has been removed. Register an extension on the app.runtime.header.right extension point instead.

Portals intended for internal use (e.g. the bottom drawer), I didn't replace with new extension points but with teleports. Also, extensions of type CustomComponentExtension can now have properties via the new componentProps property.
