RFR: 8320533: Adjust capstone integration for v6 changes [v3]

[Galder Zamarreño]

> FYI @theRealAph
> 
> It includes a couple of commits to integrate with Capstone v6 while still working with Capstone v5 and before:
> * `CAPSTONE_ARCH` for aarch64 is now `CS_ARCH_AARCH64` instead of `CS_ARCH_ARM64`. See [this document](https://github.com/Rot127/capstone/blob/v6-release-guide/docs/cs_v6_release_guide.md) to understand motivation for this Capstone change.
> * The `-Daarch64` macro was getting in the way and was causing invalid C to be produced. Undefined it before including `capstone.h`. Thx @rwestrel for suggesting the fix!
> * Enhanced autoconf to select the right aarch64 arch name depending on the capstone library in use.
> 
> Here's some output to demonstrate autoconf:
> 
> 1. If using capstone v6, you will see:
> 
> checking capstone aarch64 arch name... AARCH64
> 
> 
> 2. If using capstone v5, or earlier, you will see:
> 
> checking capstone aarch64 arch name... ARM64
> 
> 
> With v5 or earlier, the compilation error in the config log file is the expected one:
> 
> 
> configure:142906: checking capstone aarch64 arch name
