[FEATURE] Set different shares for different engines

### Search before asking

- [X] I have searched in the [issues](https://github.com/apache/kyuubi/issues?q=is%3Aissue) and found no similar issues.

### Describe the feature

We hope that spark can be shared at the use level, and trino can be shared at the pool level, but kyuubi has not yet provided the setting for configuring the sharing level according to the engine type
**"kyuubi.engine.share.level"** is globally effective, and session conf is only for sessions alone. It is hoped to add different sharing levels according to engine settings. For example: **"kyuubi.engine.{spark|trino|flink}.share.level"**
The priority is : session conf > kyuubi.engine.{spark|trino|flink}.share.level > kyuubi.engine.share.level

### Are you willing to submit PR?

- [x] Yes. I would be willing to submit a PR with guidance from the Kyuubi community to improve.
- [ ] No. I cannot submit a PR at this time.

Start by tracing how kyuubi.engine.share.level and session configuration are read for Spark, Trino, and Flink engines. Verify how an engine-specific setting should interact with the global setting and confirm the stated precedence: session configuration, then engine-specific configuration, then the global default.
