winsound: drop the imports the NUL-safe PlaySound left behind - #8554

Extract the shared UTF-16 conversion.

Both branches perform the same as_wtf8() and encode_wide() conversion. Extract this logic into one helper, then keep the match focused on obtaining the PyStr.

As per coding guidelines, when branches differ only in a value but share common logic, extract the differing value and call the common logic once.

Proposed refactor

+fn encode_wide(s: &PyStr) -> Vec<u16> {
+    let s = s.as_wtf8();
+    let mut buf = Vec::with_capacity(s.len() + 1);
+    buf.extend(s.encode_wide());
+    buf
+}
+
 let path = match sound.downcast_ref::<PyStr>() {
-    Some(s) => {
-        let s = s.as_wtf8();
-        let mut buf = Vec::with_capacity(s.len() + 1);
-        buf.extend(s.encode_wide());
-        buf
-    }
+    Some(s) => encode_wide(s),
     None => {
         // existing __fspath__ handling
-        let s = result.downcast_ref::<PyStr>()?;
-        let s = s.as_wtf8();
-        let mut buf = Vec::with_capacity(s.len() + 1);
-        buf.extend(s.encode_wide());
-        buf
+        encode_wide(result.downcast_ref::<PyStr>()?)
     }
 };

In `@crates/vm/src/stdlib/winsound.rs` around lines 106 - 112, Extract the
repeated WTF-8-to-UTF-16 conversion into a shared helper near the affected
winsound logic, and have both branches provide only their obtained PyStr value
to that helper. Update the match around the sound argument and the corresponding
logic at the second affected location so as_wtf8 and encode_wide are performed
once in the common path, preserving the existing buffer behavior.
