Provide additional flexibility in footer component about govuk-components HOT 2 CLOSED

Discussing this with @peteryates, there’s additional complexity here due the nature of the underlying CSS layout, and the various assumptions it makes. Therefore, to enable reasonable customisation, but without allowing a mixture of options that would create broken layouts, suggest the following options (or similar):

• meta_items: Array. items for use in the meta section of the footer.
• meta_items_title: String. Title for a meta item section. Defaults to ‘Support links’
• meta_content: Slot? Content to add to the meta section of the footer. This will appear below any links specified using meta_items option.
• meta_licence: String/Boolean. Licence text. Defaults to OGL licence (OGL logo plus the text ‘All content is available under the Open Government Licence v3.0, except where otherwise stated’). If this option is used, the OGL SVG logo is removed. If set to false, both the SVG logo and text span are removed.
• meta: Slot. Custom HTML that appears to the left of the crest. If this slot is used, all of the above settings are ignored, and defaults overwritten.
