enhance needless_collect
...
Updates `needless_collect` to lint for collecting into a method or
function argument thats taking an `IntoIterator` (for example `extend`).
Every `Iterator` trivially implements `IntoIterator` and colleting it
only causes an unnecessary allocation.

needless_collect: For BTreeMap and HashMap lint only is_empty
...
- `len` might produce different results than `count`
- they don't have `contain` but `contains_key` method

Lint against needless uses of collect()
...
Handles cases of `.collect().len()`, `.collect().is_empty()`, and
`.collect().contains()`. This lint is intended to be generic enough to
be added to at a later time with other similar patterns that could be
optimized.
Closes #3034
