[HIPIFY] Initial support of translation to ROCm

+ Option '-roc' is added to translate to ROCm instead of HIP
+ Update hipification mechanism accordingly
+ Populate all translation maps with additional field for ROCm identifiers
+ There are 4 degrees of CUDA support now: full support, only by HIP, only by ROCm, unsupported
