Add non-functional WheelDistribution.locate_file() method (#11685)

importlib.metadata.Distribution was always meant to be a proper ABC with
API enforcement, but this enforcement was never added (probably due to
Python 2.7 compatibility concerns). Upstream would like to fix this
wart, so let's define a locate_file() method that simply raises
NotImplementedError as permitted.
