Clean up driver dynamic library logic

[ftynse]

We have two places where we load libamdhip64.so or equivalent and throw from C++ invoked from python, aborting the entire process.

wave/wave_lang/kernel/wave/execution_engine/wave_hip_runtime.cpp

Line 62 in 9810652

module = dlopen("libamdhip64.so", RTLD_NOW);

wave/wave_lang/kernel/wave/runtime/runtime.cpp

Line 67 in 9810652

module = dlopen("libamdhip64.so", RTLD_NOW);

This should be cleaned up:

• let's not duplicate code, especially with platform-specific logic;
• provide a graceful mechanism to catch this error without aborting the process
