Turn default document info bars into bundle contributions

The default document info bars are hardcoded in the nuxeo-document-info-bar element. After the new info bar slot is introduced under WEBUI-325, those elements should be made slot contributions in the Web UI bundle, allowing them to be reordered or disabled on Designer. To achieve this, we must consider:

1. Extracting the already existing info bars into dedicated custom elements.
2. Fixing the styles, as some info bar custom elements have their own styles, but the nuxeo-document-info-bar itself also forces custom styles. We could also extract a dedicated element with a slot to handle any common styles and logics for info bars
3. Make the newly created info bar elements bundle contributions for the slot introduced in WEBUI-325.
