rust: add `impl_flags!` macro for defining common bitflag operations
We have seen a proliferation of `mod_whatever::foo::Flags` being
defined with essentially the same implementation for `BitAnd`, `BitOr`,
`.contains()` etc.
This macro aims to bring a solution for this, allowing to generate these
methods for user-defined structs. With some use cases in KMS and upcoming
GPU drivers.

[ Implemented missing `BitXorAssign<$flag> for $flags`. Sorted
`impl`s. Removed prelude addition for now -- I asked the team and they
also felt it wasn't needed. We can always add it later on if needed.
Fixed intra-doc link (by removing the sentence since it was superfluous
anyway). Simplified `empty()` title. Reworded commit slightly. Added
docs to enum variants in example to avoid 'missing_docs' lint when used
in actual code. - Miguel ]
