Add Spark 3.5.9 support for CreateNamedStruct shims (NVIDIA#15388)

### Description

`CreateNamedStructShims` and `GpuCreateNamedStructSuite` were introduced
while Spark 3.5.9 support was being added, so their shim metadata
omitted the `359` entry. As a result, common code in a Spark 3.5.9 build
cannot resolve `CreateNamedStructShims`.

This change adds the missing `{"spark": "359"}` entry to both files.
Spark 3.5.9 now uses the same legacy `name.toString` behavior as the
other Spark 3.5.x shims, and the existing `GpuCreateNamedStructSuite`
runs for this build version.

Validation:

- `mvn -Dbuildver=359 -DskipTests -pl sql-plugin -am install` — `BUILD
SUCCESS`
- `mvn -Dbuildver=359 -pl sql-plugin test
-Dsuffixes='.*GpuCreateNamedStructSuite'` — 1 test passed
