Kernel name demangle

[JoseSantosAMD]

Closes #142

[coleramos425]

In order for demangler to work in CLI analysis mode we'll need to reference kernel_name_shortner() from inside profile mode. Thus overwriting mangled KernelNames in CSVs (as part of profiling pipeline).

It seems most logical to move the --kernelVerbose flag into profile mode and give the user the option to toggle the demangling from here

@JoseSantosAMD isn't there a new package required for llvm-cxxfilt? If it's a Python package we need to make sure it's included in the requirements.txt, otherwise we'll have to make sure it's listed in our docs.

No, it uses /opt/rocm/llvm/bin/llvm-cxxfilt
