feat(atomic): add heading function for lit components

[y-lakhdar]

• Added heading function to replace the <Heading> functional component.
• Renamed hidden.tsx function component to stencil-hidden.tsx (to be consistent)

Usage

with Stencil

<Heading level={level} class="truncate">
  {label}
</Heading>

with Lit

html`${heading(
  {level, class: "truncate"},
  label
)}`

Notes

Using unsafeStatic since we need to interpolate non-literal statics.

ATM this PR actually renames both heading.tsx to stencil-heading.tsx and hidden.tsx to stencil-hidden.tsx.

The hidden renamal seems out of scope, but I guess it will have to be done anyways, so it's not a big deal.

Yeah, sorry. It was something I forgot to do in previous PRs
