Update binutils code to the latest binutils

[XVilka]

Until we figured how to reuse the code using linking or Meson subprojects, it's better to update the binutils code in Rizin to support more instructions. The current code is very old.

Pieces from binutils-gdb were used in many different places (opcodes library/libopcodes, libiberty, BFD library):

• librz/asm/arch/arc/gnu/ (will be removed) during the capstone auto-sync for ARC
• librz/asm/arch/arm/aarch64/
• librz/asm/arch/cris/gnu/
• librz/asm/arch/lanai/gnu/
• librz/asm/arch/mips/gnu/ (will be removed) RzIL MIPS Uplifting #3508
• librz/asm/arch/nios/gnu/
• librz/asm/arch/xtensa/gnu/ (will be removed) during the capstone auto-sync for Xtensa by @imbillow
• librz/asm/arch/vax/
• librz/asm/arch/tricore/gnu/ (will be removed) Capstone@next TriCore #3463
• librz/asm/arch/sparc/gnu/ (will be removed) during the capstone auto-sync for RISC-V: auto-sync progress tracker: Refactor and implement architectures capstone-engine/capstone#2015
• librz/asm/arch/riscv/ (will be removed) during the capstone auto-sync for RISC-V: auto-sync progress tracker: Refactor and implement architectures capstone-engine/capstone#2015
• librz/asm/arch/hppa/gnu/ (will be removed) HP PA-RISC: Migrate to Capstone and add basic analysis #4469

Please be careful, since some of these copied sources could have custom modifications after they were imported - I recommend to check the git history of Rizin and Radare2 to see them. Good example how to do that is in a similar issue for libmagic: #721

I was trying to update hppa/gnu. It compiles fine, but they seem to have changed their format a bit and removed braces for if statements with one lines, making a huge diff at some places. Should I do anything with that?

IMHO the code should be taken as-is from upstream and moved to a subproject. If necessary (it is necessary likely) we will provide a custom meson.build as done for others subprojects to create a meson object that compiles the right files with the right config.

i don't expect much work to happen here any time soon. Also, as I will refactor plugins hopefully immediately after 0.4.0, it would be better to have the dependency to binutils limited to those plugins.
