Fix Enumerator::Lazy#with_index

* Make it correctly handle lambdas
* Make it iterate over the block if block is given

The original implementation was flawed, based on lazy_set_method
instead of lazy_add_method.

Note that there is no implicit map when passing a block, the return
value of the block passed to with_index is ignored, just as it
is for Enumerator#with_index. Also like Enumerator#with_index,
when called with a block, the return value is an enumerator without
the index.

Fixes [Bug #16414]

Fix Enumerator::Lazy#{to_enum,enum_for} where method is defined in Lazy

Previously, passing to_enum/enum_for a method that was defined in
Lazy itself returned wrong results:

  [1,2,3].to_enum(:map).to_a
  # => [1, 2, 3]
  [1,2,3].lazy.to_enum(:map).to_a
  # => []

I'm not sure why methods that are designed to be lazy do not work
with to_enum/enum_for.  However, one possible way to work around
this bug is to have to_enum/enum_for use the implementation found
in Enumerable/Enumerator, which is what this commit does.

While this commit works around the problem, it is a band-aid, not a
real fix.  It doesn't handle aliases of Enumerable::Lazy methods,
for instance.  A better fix would be appreciated.

Previously, Enumerator::Lazy#with_index was not defined, so it
picked up the default implementation from Enumerator, which was
not lazy.

Based on earlier patch from nobu.

Fixes [Bug #7877]
