Make the @as casts actually apply

emmylua only parses the inline cast as `--[[@as T]]`, the spaced form
`--[[ @as T ]]` is treated as a plain comment, so all 149 of them were
doing nothing.

LuaGuiElement.style is a union because a style name can be assigned to
it, so reading it back needs the cast.
