perf: Add PERF_SAMPLE_BRANCH_CALL

Add a new branch sample type to cover only call branches (function calls).
The current ANY_CALL included direct, indirect calls and far jumps.

We want to be able to differentiate indirect from direct calls. Therefore
we introduce PERF_SAMPLE_BRANCH_CALL. The implementation is up to each
architecture.
