Add ParseException constructors to API

ParseException constructors are used by both platform and mainline
module code, so they can't be package-private.
Removing dependencies on either side is not possible as the class
itself is part of the public API, and supports APIs on both sides.

Having the constructors part of the API makes the class usable by both
sides.

Test: CtsNetTestCases for APIs using the exception
