Add additional manifest attributes to handle purpose declaration app 

compatibility.

Adding requiresPurposeTargetSdkVersion attribute under <permission> to
ensure only apps that target a specific SDK version or above require
purpose for a given permission. Also adding maxTargetSdkVersion on
<valid-purpose> for deprecating purposes in the future platform
releases.
