perf annotate: Split out util/disasm.c



The util/annotate.c code has both disassembly and sample annotation
related codes.  Factor out the disasm part so that it can be handled
more easily.

No functional changes intended.

Committer notes:

Add missing include env.h, util.h, bpf-event.h and bpf-util.h to
disasm.c, to fix things like:

  util/disasm.c: In function ‘symbol__disassemble_bpf’:
  util/disasm.c:1203:9: error: implicit declaration of function ‘perf_exe’ [-Werror=implicit-function-declaration]
   1203 |         perf_exe(tpath, sizeof(tpath));
        |         ^~~~~~~~
