Length conversion should use Feet + Inches instead of Feet with decimal point

[MicrosoftIssueBot]

Problem Statement
Today, length converter shows decimal values for feet, while in practice, feet + inches are oftentimes used.

Evidence or User Insights
Observation of current behavior and customary use in U.S. and U.K. Details on foot (unit).

Proposal
When converting to feet, in addition to showing the decimal conversion, also include "feet + inches", which is more commonly used when working in this unit. For example, when converting 230cm, Calculator shows 7.545932 feet. It would be more useful if it would also show 7' 6.55" (feet with inches).

Possibly dependent on #379.

Goals

• Additionally show the "feet and inches" conversion when working with feet in length converter.

Non-Goals

• Remove decimal representation of values in feet

Low-Fidelity Concept

Ideally, it should show both, the non-default notation probably in the "About equal to" section.

We reviewed the pitch and would love to explore this idea further! The pitch is a great start, but there are still some open questions. I am moving this issue into planning to iron out some of those details and I created calculator-specs/feetinches to track progress. A human will follow up with some feedback on your pitch shortly. Keep in mind that not all ideas that make it into the planning phase are guaranteed to make it to release. For more information on next steps, check out our spec workflow.

This would be a great feature. It would also be really nice to be able to input fractions of an inch. If I'm reading a tape measure as 6⅞", it would be nice to input that directly when converting to metric.
