Feat: Add datasource tracing with P6Spy.

[maciejwalkowiak]

📜 Description

Adds datasource tracing with p6spy.

In comparison to #1095, we do not rely on any 3rd party integration with Spring, we also do not provide any custom integration with Spring. Instead, we use the Java ServiceLoader mechanism to provide an implementation of P6Spy's JdbcEventListener.

As a result, to use P6Spy and Sentry integration with Spring Boot application, it's enough to:

1. Prefix JDBC url with p6spy, for example:

spring.datasource.url=jdbc:p6spy:hsqldb:mem:testdb

2. For drivers that do not accept prefixes (like HSQLDB), configure driver-class-name property:

spring.datasource.driver-class-name=com.p6spy.engine.spy.P6SpyDriver

3. Add dependency to sentry-p6spy.

💡 Motivation and Context

Missing piece.

💚 How did you test it?

Integration tests and sample app.

📝 Checklist

• I reviewed the submitted code
• I added tests to verify the changes
• I updated the docs if needed
• No breaking changes

🔮 Next steps

Depending on the feedback we get, we may also add integration with https://github.com/ttddyy/datasource-proxy, but this will require more changes in Spring configuration, as we would need to post-process the datasource bean like here
