This PR implements semantic checks for
mutrestrictions proposed in RFC 3323, as part of the related GSoC project.It lowers field restriction information from HIR into
rustc_middle::ty::FieldDefand adds a MIR-level lint that rejects restricted field mutations and struct expressions. As parsing (#156824) and path resolution (#159125) have already been implemented, this PR provides a working implementation ofmutrestrictions.Tracking issue: #105077
