Make _useKResponsiveElement composable public and Remove KResponsiveElementMixin

[AlexVelezLl]

Product

KDS, Kolibri (Studio and KDP doesnt seem to be using the KResponsiveElementMixin).

Description

Transition the internal composable _useKResponsiveElement to a public-facing composable named useKResponsiveElement. Then, remove the KResponsiveElementMixin mixin from the codebase. This involves the following steps:

• Rename _useKResponsiveElement.js file to useKResponsiveElement.js.
• Update all internal references to use the new file name.
• Migrate all internal references of KResponsiveElementMixin to use the new useKResponsiveElement composable.
• Remove the KResponsiveElementMixin.js file.
• Create a new documentation page for useKResponsiveElement.
• Remove the old documentation page of KResponsiveElementMixin.

The Value Add

After this, we will able to replace all KResponsiveElement mixins with this composable. This aligns with our plan of adopting composables over mixins.

Hey @lokesh-sagi125, I think the issue is suitable for contribution, however @AlexVelezLl assigned himself some time ago so I'm not sure if there's some work in progress. Let's hear from Alex first where things are.
