The pressure stall information (PSI) special files in /proc/pressure currently don't have a separate file context, and so default to proc_t. Since users need read/write permissions to those files to use PSI, and handing out blanket permissions to proc_t is strongly discouraged, introduce a new proc_psi_t label, as well as interfaces for it.
