perf: util: use capstone disasm engine to show assembly instructions
Currently, the instructions of samples are shown as raw hex strings
which are hard to read. x86 has a special option '--xed' to disassemble
the hex string via intel XED tool.
Here we use capstone as our disassembler engine to give more friendly
instructions. We select libcapstone because capstone can provide more
insn details. Perf will fallback to raw instructions if libcapstone is
not available.
The advantages compared to XED tool:
* Support arm, arm64, x86-32, x86_64 (more could be supported),
xed only for x86_64.
* Immediate address operands are shown as symbol+offs.
