Add description or add placement option for meta and add possibility for font size 16

[BorghildSelle]

Hello,
we would like to suggest a new feature for an description option to be sent to Textfield, similar to https://aksel.nav.no/komponenter/core/textfield#textfielddemo-description
We sometimes need to provide some extra information to the user, where ideally it would not be in the label but implemented similar to helpertext (aria-describedby).
The meta field is placed too far to the right to fit our needs, as the text might be a regular sentence.
This is how we think it could look like:

We also would like to request an possibility to set font size to 16px, as this is the base size for equinor.com
And maybe also Textarea can be exported like Input?
