rust: pin-init: internal: generate brace in macro for init code blocks

`init!` support interleaving code execution and initialization, and code
execution is done using `_: { ... }` syntax. If the code inside block is a
single statement, Rust may add a lint about unused braces, but the
suggestion will be incorrect as block is required by pin-init.

Currently we use `unused_brace` to suppress this, but this affect
everything nested inside as well. Use an alternative approach by generating
the block from the macro, then rustc will know to not emit the lint.
