perf record: Add HEADER_BRANCH_STACK tag
This patch adds a new feature bit, namely,
HEADER_BRANCH_STACK. When present, it indicates
that sample records may contain branch stack.
This could be useful to a viewer to switch to
branch mode without having to parse all the
samples or without a specific cmdline option.
This will be used in a subsequent patch to
enhance perf report with branch stacks.
