Description

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Motivation

Using https://www.graalvm.org/ to build a native-image for pulsar-admin reduces the running time.

Comparison of running time:
```
❯ ./native-pulsar-admin.sh
+ echo native-pulsar-admin
native-pulsar-admin
+ ./target/./native-pulsar-admin ../conf/client.conf tenants list
public
pulsar

real 0m0.264s
user 0m0.208s
sys 0m0.049s
+ echo ----------------
----------------
+ echo 'default pulsar-admin'
default pulsar-admin
+ ../bin/pulsar-admin tenants list

real 0m2.429s
user 0m4.667s
sys 0m0.318s
```

This `native-pulsar-admin` reduces real by 9 times compared to `pulsar-admin.sh`, this is a benefit.

BTW, Graalvm cannot support cross-compilation, we must use different platforms to build different native-image.

Research direction

Start by reproducing the commands in native-pulsar-admin.sh, comparing target/./native-pulsar-admin with ../bin/pulsar-admin and reviewing the GraalVM native-image requirements. Done would require a defined, platform-specific way to build native pulsar-admin binaries, but the issue does not specify build files, supported platforms, tests, or acceptance criteria.
