RFR: 8316694: Implement relocation of nmethod within CodeCache [v35]

[Chad Rakoczy]

> This PR introduces a new function to replace nmethods, addressing [JDK-8316694](https://bugs.openjdk.org/browse/JDK-8316694). It enables the creation of new nmethods from existing ones, allowing method relocation in the code heap and supporting [JDK-8328186](https://bugs.openjdk.org/browse/JDK-8328186).
> 
> When an nmethod is replaced, a deep copy is performed. The corresponding Java method is updated to reference the new nmethod, while the old one is marked as unused. The garbage collector handles final cleanup and deallocation.
> 
> This change only slightly modifies existing code paths and therefore does not benefit much from existing tests. New tests were created to test the new functionality
> 
> Additional Testing:
> - [ ] Linux x64 fastdebug all
> - [ ] Linux aarch64 fastdebug all
> - [ ] ...
