Specify root elements for apex-info-list
Otherwise, xsdc generates parser/writer code for apex-info as well,
which is unnecessary and increases code size.
For example, on aosp_cf_x86_64_phone, libvintf.so decreases from 695000
to 693472.
Regarding *-api changes: manually updated to reflect the change. Two
methods are removed from XmlParser/XmlWriter. It's okay because removed
methods don't belong to any API surface.
Bug: n/a
Test: m apexd libvintf
