perf intel-pt: Insert callchain context into synthesized callchains

perf intel-pt: Insert callchain context into synthesized callchains

commit 242483068b4b9ad02f1653819b6e683577681e0e upstream.

In the absence of a fallback, callchains must encode also the callchain
context. Do that now there is no fallback.
