[PATCH 0/6] rust: binder: reduce `as` casts

[Tamir Duberstein]

Follow up on the treewide Clippy lint series [1]. The Rust Binder
driver retains local allows for `clippy::ptr_as_ptr`,
`clippy::ref_as_ptr`, `clippy::as_underscore`, and
`clippy::cast_lossless` even though those lints are enabled for the
rest of the kernel.

Fix the Binder violations and remove those allows one lint at a time.
The first two patches reduce related `as` casts outside those lint
enablements: use the strict provenance APIs for Binder
pointer-to-integer conversions now that they are available at the Rust
MSRV, and transmute embedded transaction data directly instead of
round-tripping a reference through raw pointer casts.
