<summary>Changes</summary>
Reland: https://github.com/llvm/llvm-project/pull/95456
This patch improves the ROCDL gpu serialization API by:
- Introducing the enum `AMDGCNLibraries` for specifying the AMD GCN device code libraries to use during linking.
- Removing `getCommonBitcodeLibs` in favor of `AMDGCNLibraries`. Previously `getCommonBitcodeLibs` would try to load all AMD GCN bitcode librariesm now it will only load the requested libraries.
- Exposing the `compileToBinary` method and making it virtual, allowing downstream users to re-use this method.
- Exposing `moduleToObjectImpl`, this method provides a prototype flow for compiling to binary, allowing downstream users to re-use this method.
- It also avoids constructing the control variables if no device libraries are being used.
