[PATCH v2 0/2] Remove `ArcBorrow`

[Wedson Almeida Filho <wedsonaf@gmail.com>]

From: Wedson Almeida Filho <walmeida@microsoft.com>

In this small series we remove `ArcBorrow<'_, T>` and replace it with
`&WithRef<T>`, which we used to call `ArcInner` --  it is renamed
because it is now public, so we chose a more meaningful name.

This simplifies the code because we remove a type and have simpler
syntax to refer to borrowed arcs: `ArcBorrow<'a, T>` vs 
`&'a WithRef<T>`.

This became possible when we adopted GATs in 2021 but we only realised
it recently (thanks Boqun!), more details on this zulip thread:

Changes v1 -> v2:
* Moved the definition of `WithRef` to where `ArcBorrow` was.
* Updated documentation of `as_arc_borrow`.

Wedson Almeida Filho (2):
  rust: arc: rename `ArcInner` to `WithRef`
  rust: arc: remove `ArcBorrow` in favour of `WithRef`
