[ISSUE #4670] Docker build failed due to a low JDK version

[Pil0tXia]

Fixes #4670.

Motivation

https://github.com/Pil0tXia/eventmesh/actions/runs/7238476046/job/19719334574

Modifications

• Switch builder JDK version from jdk8 to jdk11 and switch container JDK version from jdk8 to jre11. Compile the code in two stages using JDK11 and JDK8, and run the container in a Java8 environment. Optionally, provide a script for running in a Java11 environment.
• Using JRE instead of JDK as a runtime envrionment can reduce 300MB+ imgae size.
• Modify start.sh to support selecting an available version between Java 8 and Java 11, and set the VM options accordingly.
• Fix get_pid functionality in docker.
• Streamline outdated Java exec locating logic.

Docker deployment & compilation documents will be updated later.

These runtime environments are tested:

• Standalone deployment with Java 8 (Jdbc GrammarSource generate under JDK11) PASSED

• Docker deployment with Java 11 PASSED with Netty warning deprecated usage: [Bug] Netty Reflective setAccessible(true) warning under JDK11 #4676
