RFR: 8336874: WhiteBoxAPI: assert(!method->is_abstract() && (osr_bci == InvocationEntryBci || !method->is_native())) failed: cannot compile abstract/native methods

[Sonia Zaldana Calles]

Hi all, 

This PR addresses [8336874](https://bugs.openjdk.org/browse/JDK-8336874) ensuring enqueuing an abstract method for compilation doesn't hit an assert with WhiteBox. 

Testing: 
- [x] Added test case passes. 

Thanks, 
Sonia
