Check if we need a mixin for getting specific font maps from the typography scale

[owenatgov]

What

Get feedback from the community to assess if there's a need for a mixin to target a specific font map within the typography scale. Instead of collecting and setting all font-size's and line-height's by breakpoint, this would find a specific map within a specified scale point map based on a specified breakpoint within that map.

Why

This was an initial proposal following https://github.com/alphagov/govuk-frontend/issues/3837 however we came to the conclusion that we don't have enough evidence to know if this is necessary. We additionally think that most scenarios that would need this would be solved by the wider typography scale work and better documentation.

To assess these hypotheses and see if this mixin would still be useful, we will ask the community about if the new scale is meeting their needs.
