With this CL, Intent#ACTION_MY_PACKAGE_REPLACED will
not only update the visibility of the setup activity but
also reconstruct additional subtypes.

This is important because the system always removes all
the additional subtypes whenever the package is updated.

BUG: 15890448

This CL consolidates the initialization logic for additional
subtypes so that each additional subtypes can have predictable
subtype ID regardless of OS version.

Previously subtype IDs for additional subtypes are calculated
differently depending on the running OS version with hoping it
minimizes the risk of compatibility issues.  However, it is
getting harder and harder to maintain slightly different
logic between OSes. Thus we decided to unify the logic into
that in KitKat even though it may causes some breaking changes.

Note that the actual extra values that are used to instantiate
InputMethodSubtype object are still determined on the fly
depending on the running OS version. However these actual
extra values are no longer used for the subtype ID calculation.

...otherwise we can't recompute the composition when we
change scripts.

This also fixes when we register that we need to take note
that the current subtype was used. Luckily this is a good
occasion for some cleanup that I've wanted to do for some
time: use InputTransaction for onTextInput (with the goal
to ultimately remove it entirely)
