Feat: Adds tokens to EmptyState

[eduardoformiga]

What's the purpose of this pull request?

This PR applies the new Theming structure to EmptyState: new scoped tokens linked to global ones.

How does it work?

This PR uses local variables to parameterize the EmptyState properties, then connects these scoped tokens to the global ones.

Local token	Default value/Global token linked
--fs-empty-state-height	100%
--fs-empty-state-min-height	50vh
--fs-empty-state-padding	0 var(--fs-spacing-8)
--fs-empty-state-bkg-color	var(--fs-color-neutral-bkg)

Rounded Variant

Local token	Default value/Global token linked
--fs-empty-state-border-radius	var(--fs-border-radius)

Related Components
