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).
