assorted filter pill fixes

[gwyneplaine]

• resolves Filter items are not very SR friendly #5939 by adding aria-label and aria-description to pill
• fixes autoFocus always being on in text field Filter component
• revert redundant status="role" on editDialog
• Added containerProps prop to Pill component in design-system that are spread onto the container element, props are now spread onto the PillButton element by default.
• Ensured trigger.ref is applied to PillButton ref and not the pill container ref (which previously broke focus)
• Fixed issue with filters not always being removable (due to undocumented breaking change with Next)
