[SWDEV-503520] Add amdsmi_get_rocm_version() in python library (#76)

Changed amdsmi_get_rocm_version() to be an API in the python library only. 
Updated usage and version detection
Updated path detection of librocm-core.so
Updated docs to reflect both amdsmi_get_rocm_version and amdsmi_get_lib_version() do not require initialization.
