longsonr 5b9df67d2e Bug 1652395 - Replace 'typedef' by 'using' in SVG and SMIL code r=dholbert
Also removes some mozilla:: where its no longer needed

Note that this patch was created by running

sed -e -i '.bak' 's/typedef ([a-zA-Z0-9:]+) ([a-zA-Z0-9:]+)/using \2 = \1/'

and then fixing up a few cases that didn't work.
