Add GraalVM native-image support to azure-core-http-jdk-httpclient

[Jeroen Benckhuijsen (jfbenckhuijsen)]

Description

Adds native compilation (graal) info to the azure-core-http-jdk-httpclient module, which was lacking these settings. The settings were mirrored from the netty version which had these changes. Correct behavior was validated in a external app empirically.

Pull request overview

This PR adds GraalVM native-image metadata to azure-core-http-jdk-httpclient so the JDK-based HttpClientProvider can be discovered/initialized correctly when building and running as a native image, aligning behavior with the existing azure-core-http-netty module.

Changes:

• Added GraalVM reflection metadata (reflect-config.json) for com.azure.core.http.jdk.httpclient.JdkHttpClientProvider.
• Added GraalVM runtime-initialization configuration (native-image.properties) for JdkHttpClientProvider$GlobalJdkAsyncHttpClient.
• Documented the change in the module CHANGELOG.md.
