Migrate margin and padding helpers to tailwind (#30043)
This will conclude the refactor of 1:1 class replacements to tailwind,
except `gt-hidden`. Commands ran:

```bash
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-0#tw-$1$2-0#g'   {web_src/js,templates,routers,services}/**/*
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-1#tw-$1$2-0.5#g' {web_src/js,templates,routers,services}/**/*
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-2#tw-$1$2-1#g'   {web_src/js,templates,routers,services}/**/*
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-3#tw-$1$2-2#g'   {web_src/js,templates,routers,services}/**/*
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-4#tw-$1$2-4#g'   {web_src/js,templates,routers,services}/**/*
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-5#tw-$1$2-8#g'   {web_src/js,templates,routers,services}/**/*
