Migrate base::Value::GetList() to base::Value::GetListDeprecated(): 1/N.

GetList() will be reimplemented in a future CL with an updated
signature, so existing uses need to be renamed out of the way.

Unlike TakeList() and TakeDict(), GetList() is used quite widely. This
CL migrates a number of uses using the following set of automated steps:

sed -i "s|->GetList()|->GetListDeprecated()|g" \
    $(git gs "GetList()" --name-only)
git checkout -- base/values_unittest.cc third_party/dom_distiller_js
git cl format
