rust: extract `bitfield!` macro from `register!`
Extract the bitfield-defining part of the `register!` macro into an
independent macro used to define bitfield types with bounds-checked
accessors.
Each field is represented as a `Bounded` of the appropriate bit width,
ensuring field values are never silently truncated.
Fields can optionally be converted to/from custom types, either fallibly
or infallibly.
Appropriate documentation is also added, and a MAINTAINERS entry created
for the new module.
Two minor fixups are also applied: the private accessors are inlined,
and a couple of missing fully qualified types in the macro are fixed.
