Adds fallible versions of MessageBox's helper factories, ports
DeprecatedString, and rewrites build() to be both fallible and

creation to position properly as a Dialog before being shown.
We have a new, improved string type coming up in AK (OOM aware, no null

mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
