"Current pressure state" definition and cardinality are confusing

[rakuco]

https://w3c.github.io/compute-pressure/#dfn-current-pressure-state is currently defined as a per-global string.

However:

• Its value is not set anywhere in the spec.
• All locations in https://w3c.github.io/compute-pressure/#contributing-factors that reference/read its value do not provide a corresponding global.
• The way it is referenced in https://w3c.github.io/compute-pressure/#dfn-state makes it sound like this concept is per-source type, not per global, at the very least.
