Add Windows ARM64 builds

This PR adds Windows `aarch64` builds to CI. These builds are similar
to Windows `x86_64` builds with the following notes:

1. Java 21 (the lowest version available on `windows-11-arm` GH runner)
   is used to compile the Java part of JDBC, so it is the lowest version
   the driver can be loaded with

2. `aarch64` binaries are not included into the main "universal" JAR,
   instead the `windows_aarch64` Maven classifier need to be used to
   fetch it:

```xml
<dependency>
    <groupId>org.duckdb</groupId>
    <artifactId>duckdb_jdbc</artifactId>
    <version>1.4.1.0</version>
    <classifier>windows_aarch64</classifier>
</dependency>
```

3. DuckDB extensions for Windows `aarch64` are not available at the
   moment, so some of the tests (e.g. Spatial ones) are failing.
