perf tools: Dump callchain context marker names
These are hard to interpret in the raw output because they are printed
as hex but are defined in perf_event.h as decimal. Make it much easier
to read the raw callchains by just printing their names.
For example:
$ perf report -D
1798195372321 0x4638 [0xb0]: PERF_RECORD_SAMPLE(IP, 0x4002): 44922/44922: 0x7c8046dd3400 period: 120218 addr: 0
... FP chain: nr:12
..... 0: fffffffffffffe00 (PERF_CONTEXT_USER)
..... 1: 00007c8046dd3400
..... 2: 00007c8046db86d3
