Fixes: #9711
Issue link: https://github.com/spring-projects/spring-integration/issues/9711
The `SmbConfig.getUrl(_includePassword)` uses `URI.toASCIIString()` which has all the parts of the URI encoded.
Then this string is used by the `SmbShare` for its super constructor, which, in turn, calls `new URL()`
leading, essentially, to a second encoding round.
* Add `SmbConfig.rawUrl()` methods to return an `smb://` url as a plain string.
* Use this new API in the `SmbShare` for a delegation constructor
* Modify some tests to reflect and cover new behavior
**Auto-cherry-pick to `6.3.x`**
