[TASK] Migrate page title inline editor to web component

This patch migrates the inline editor used to modify a page's table to a
standalone web component. This allows to cleanup the original
`@typo3/backend/page-actions` module and to fix state cross-dependencies
within said module.

The whole functionality is considered to be used for internal purposes
only. Therefore, the deprecated method
`\TYPO3\CMS\Backend\Template\ModuleTemplate->header()` is not adjusted, rendering a very unlikely enabled page title editing unusable.
