[ABI] Completely reworked instruction DB and generators

Browse Source 
* Instruction database is now part of asmjit to keep it in sync
  * X86/X64 ISA data has been reworked, now in a proper JSON format
  * ARM32 ISA data has been added (currently only DB, support later)
  * ARM64 ISA data has been added
  * ARM features detection has been updated
