Fixing regression in HDRnet latency due to PMU/EM profile feature activation in 30fps

A recent change (ag/20028064) has caused regression in HDRnet latency
due to activation of PMU feature and EM profile in 30fps. To mitigate this regression, this CL disables EM Profile and PMU features during the capture time (also increasing the boost profile duration from 1000ms to 2500ms).
