fix(iter): remove special case totable for map-like tables

This was originally meant as a convenience but prevents possible
functionality. For example:

  -- Get the keys of the table with even values
  local t = { a = 1, b = 2, c = 3, d = 4 }
  vim.iter(t):map(function(k, v)
    if v % 2 == 0 then return k end
  end):totable()

The example above would not work, because the map() function returns
only a single value, and cannot be converted back into a table (there
are many such examples like this).

Instead, to convert an iterator into a map-like table, users can use
fold():

  vim.iter(t):fold({}, function(t, k, v)
    t[k] = v
    return t
  end)
