Egress policer CIR packet handling with profile-capped mode

When profile-capped mode is enabled, the egress packet handling described in Egress policer CIR packet handling without profile-capped mode is modified in three ways.

First, the soft-in-profile packets received from ingress are handled in the same way as egress explicit profile in reclassification, unless the packet has been reclassified to profile out or profile exceed at egress.

Second, explicit egress inplus-profile, in-profile, and soft-in-profile packets that have not been reclassified to out-of-profile or exceed-profile at egress are allowed to be marked out-of-profile by an egress policer with a CIR not set to 0.

Third, when a policer has a CIR set to 0 (the default rate), all profile-capped packets are treated as out-of-profile independent of the initial profile state, except for exceed-profile packets that remain as exceed-profile.
