Use strings in shared library updatability attributes

Migrate from ints to Strings so we can pass codenames. Otherwise we
can't use these attributes representing a release in progress until that
release is finalized. I.e. if release T is in progress, we don't get the
correct behaviour if we use "T" in those attributes.

Also added some more tests which found some edge cases that weren't
properly handled: tests for when the shared libraries are first removed
from bootclasspath and moved to a module and then added again to the
bootclasspath via a mainline update;

In turn those tests found a bug where we would apply the logic for
onBootclasspathBefore X on devices before X which is not required.
