In order:
full BCP 47 tag, same as getBcp47()
lll-Ssss-CC
lll-Ssss
lll-CC
lll
Only strings that differ from a higher order are included, for example
if there is no script the elements will be bcp47, lll-CC, lll; if the
bcp47 string is identical to lll-CC then only lll-CC, lll.
Note that lll is only ISO 639-1/2 alpha code and CC is only ISO 3166
alpha code. If the region can not be expressed as ISO 3166 then no -CC
tags are included.
