Auto merge of #53575 - matthewjasper:unsized-is-an-error, r=estebank

Don't reduce E0161 to a warning in NLL migrate mode

This error has been on stable for a while, and allowing such code cause the compile to later ICE (since we can't codegen it). Errors `box UNSIZED EXPR` with unsized locals because it's not compatible with the current evaluation order (create the box before evaluating the expressions).

cc #53469 (fixes the ICE in this case)
