perf symbols: Remove perf_session usage in symbols layer
I noticed while writing the first test in 'perf regtest' that to just test the symbol handling routines one needs to create a perf session, that is a layer centered on a perf.data file, events, etc, so I untied these layers. This reduces the complexity for the users as the number of parameters to most of the symbols and session APIs now was reduced while not adding more state to all the map instances by only having data that is needed to split the kernel (kallsyms and ELF symtab sections) maps and do vmlinux relocation on the main kernel map.
