Separate monolithic hidden API processing from hiddenAPIFlagFileInfo
The hiddenAPIFlagFileInfo was being used for both the input and output
of bootclasspath_fragment and platform_bootclasspath and also to pass
information around to various hidden API rule methods. Supporting
multiple different uses in this way made it hard to reason about.
This change creates a separate structure for use by the
platform_bootclasspath. Follow up changes will split out other
functionality into separate types.

- verify that this does not change the contents of the apex files
