rust: bitfield: mark `Debug` impl as `#[inline]`

A `Debug` impl is for debugging and is normally not used, and therefore
should ideally not be code-generated unless used. However, Rust has no way
of knowing if a dependent crate is going to use the trait impl or not, so
unless it is marked as `#[inline]`, it will be code-generated in the
defining crate (as it is not generic).

Mark the impl generated by bitfield macro `#[inline]`, so they do not stay
in the binary unless used.

This reduces nova-core.o .text by 17% (from 151922 bytes to 125676 bytes).
