Implement eUICC error resolution.

When an operation fails with an error that the user can resolve, we
encapsulate the operation + failure in an EuiccOperation object. The
app can run the LUI to resolve the error, at which point the LUI calls
continueOperation with the original EuiccOperation and the result of
the resolution.

The resolution intent is a PendingIntent and thus the EuiccOperation
extra is safe from tampering - it is impossible to override an extra
on a PendingIntent belonging to another app.
