jit: add support for aarch64
This contribution is on behalf of Trail of Bits.
This adds support for aarch64 code generation to the JIT. This refactors the architecture-specific code emission parts of the existing x86 JIT into a new JitCompilerX86 struct, which adopts a new JitCompilerImpl trait.
The aarch64 JIT was modeled closely after the x86 JIT. Although all tests pass, the new aarch64 JIT is not ready for production use, and is gated behind a feature flag: jit-aarch64-not-safe-for-production.

Differential fuzzing this with the interpreter for 24 hours. I'll let you know if I find anything.
No detected misbehaviour from fuzzing. I've DM'd you already about some of the other issues.
Hi, I'm trying to build the ARM64 target with solana latest release, but i'm not sure if this PR cloud be merge can resolve the build error in solana?
