Research direction

Start by reading the linked XED xed-enc-asmparse.c example and comparing it with the repository's current YASM-based x86 assembler integration. Define the affected assembler entry points and tests before evaluating whether XED can replace the existing path; done means broader instruction support and improved performance are demonstrated.

Description

xed now has an example that does it: https://github.com/intelxed/xed/blob/main/examples/xed-enc-asmparse.c

This would allow us to support many instructions that are currently not supported by yasm. The performance will also be better https://github.com/Vector35/binaryninja-api/issues/6022
