The existing `mem.make_map` passes a capacity, but the builtin
`make_map` no longer takes a capacity--it was separated to
`make_map_cap` to allow for making a map without an allocation (#4340).
`core:mem` was not updated to reflect this, so any usage of `mem.make`
to make a map will currently result in a compile error.
