New timeline event renderer: add new modules (#7721)

* Added HTML parser to abstract tree nodes

* Add HTML renderer using `HtmlMessageContent`

* Add custom rendering for inline code nodes besides the monospace font

* Support `<s>` and `<strike>` too

* Add `ContentAvoidingLayoutData` support

* Improve the last block node behaviour and its integration with `ContentAvoidingLayout`

* Move `ContentAvoidingLayout` to `:libraries:ui-common` so it can be shared

* Add missing `:libraries:htmlrenderer:impl` entry in `DependencyHandlerScope.allLibrariesImpl`

* Update screenshots
