📎 Implement noStaticOnlyClass, @typescript-eslint/no-extraneous-class, unicorn/no-static-only-class

[Conaclos]

Description

Implement @typescript-eslint/no-extraneous-class, also supported by unicorn/no-static-only-class.

In contrast to @typescript-eslint/no-extraneous-class and similarly to unicorn/no-static-only-class, we should accept empty classes and classes that include only a constructor.

How should this rule behave with static blocks? https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/Static_initialization_blocks

[Conaclos]

Static blocks are static, this should not change the behavior of the rule?

[ematipico]

Should this rule be under the style group?

[Conaclos]

Should this rule be under the style group?

Maybe suspicious?

[ematipico]

This really seems a coding style rule. suspicious rules are

Rules that detect code that is likely to be incorrect or useless.

Which doesn't seem the case for this rule

[Conaclos]

Ok style seems more adequate.
