[Fix] Read only users should not be able to open a Relation picker (#10666)

## Context
ActivityTargetsInlineCell was not using the useIsFieldValueReadOnly hook
but a dedicated prop instead. To align with the rest of the
implementation I've updated that part of the code however we still want
the table/kanban views to always be in read-only mode regardless of the
hook logic so I've updated the hook to take the ContextStoreViewType
into account.
