Rollup merge of #105476 - estebank:moves-n-borrows, r=compiler-errors

Change pattern borrowing suggestions to be verbose and remove invalid suggestion

Synthesize a more accurate span and use verbose suggestion output to
make the message clearer.

Do not suggest borrowing binding in pattern in let else. Fix #104838.
