Optimize bytebuddy type description performance ( #637 )
...
### Improve the performance of type description of byte-buddy
The goal is to get the original class description at re-transform, so as to generate consistent results when the Skywalking agent is enhanced again (including implementing the EnhancedInstance interface, auxiliary fields and methods, etc.)
The previous type description used the `AgentBuilder.DescriptionStrategy.Default.POOL_FIRST` policy to get origin type description, which slows down the application startup, due to heavy I/O operations and parsing bytecode.
New way is to remove dynamic fields, methods and interfaces generated by SkyWalking Agent from `TypeDescription`, and **make it as origin type descripton**.
**Key feature** :
* No need to cache `TypeDescription` objects, less memory used.
* It only applies to the re-transform class processing flow and does not affect the startup process.
**Process flow:**
1. Find `TypeDescription` from commonly used type cache, such as primitive class.
2. Delegate to `AgentBuilder.DescriptionStrategy.Default.HYBRID`
3. Wrap `TypeDescription` by `SWTypeDescriptionWrapper` , remove fields, methods, interface generated by SkyWalking.
**Relative Issue:** https://github.com/apache/skywalking/issues/11460
