perf annotate: Make capstone_init non-static so that it can be used during symbol disassemble
symbol__disassemble_capstone in util/disasm.c calls function
open_capstone_handle to open/init the capstone.
We already have a capstone_init function in "util/print_insn.c". But
capstone_init is defined as a static function in util/print_insn.c.
Change this and also add the function in print_insn.h
The open_capstone_handle checks the disassembler_style option from
annotation_options to decide whether to set CS_OPT_SYNTAX_ATT.
Add that logic in capstone_init also and by default set it to true.
