📎 Port arrow-body-style from eslint

[dyc3]

Description

Port the arrow-body-style rule from eslint.

Suggested names:

• useAbbreviatedArrowFunction
• useArrowExpression
• noArrowImmediateReturn
• open to suggestions

The eslint rule has options, but we don't usually implement options on the first iteration of a rule. For this task, implement the functionality that is equivalent to the default option (which would be as-needed).
