safe transmute: use `Assume` struct to provide analysis options
This was left as a TODO in #92268, and brings the trait more in line with what was defined in MCP411. `Assume::visibility` has been renamed to `Assume::safety`, as library safety is what's actually being assumed; visibility is just the mechanism by which it is currently checked (this may change). ref: https://github.com/rust-lang/compiler-team/issues/411 ref: https://github.com/rust-lang/rust/issues/99571
