Rename PDFPageProxy.pageInfo to PDFPageProxy._pageInfo to indicate that the property should be considered "private"

Browse Source 
Since `PDFPageProxy` already provide getters for all the data returned by `GetPage` (in the Worker), there isn't any compelling reason for accessing the `pageInfo` directly on `PDFPageProxy`.

The patch also changes the `GetPage` handler, in `src/core/worker.js`, to use modern JavaScript features.
