Merge #10491
10491: Support nested type on replace if let with match r=k-nasa a=k-nasa

## Why

close: https://github.com/rust-analyzer/rust-analyzer/issues/8690

Now, Replacing if-let with match cant't output exhaustive patterns code.
This was because the `else` conversion used specific types (ex. Option, Result) instead of wildcards.

I thought it was more of a problem to generate non-exhaustive patterns than the benefits of using the concrete one.

How about using wildcards in `else`? 
Is this change policy acceptable?

## What

- using wildcards on `make_else_arm`
- Change test cases
