Add Mozilla's ISimpleDOM COM interfaces, which are needed

in order to fully support Windows screenreaders.

Note: it makes sense to check these files into third_party
directly (rather than pull from Mozilla's repository) because
(1) they're very small (under 500 lines total), and
(2) they're stable and unlikely to change frequently.

BUG=48185
TEST=none
