If perf is built with LIBCAPSTONE_DLOPEN=1, support dlopen-ing libcapstone.so and then calling the necessary functions by looking them up using dlsym. The types come from capstone.h which means the libcapstone feature check needs to pass, and NO_CAPSTONE=1 hasn't been defined. This will cause the definition of HAVE_LIBCAPSTONE_SUPPORT. Earlier versions of this code tried to declare the necessary capstone.h constants and structs, but they weren't stable and caused breakages across libcapstone releases.
