Linux aarch64 support for EIP196 constantine

[NickSneo]

Fixes #198

@garyschulte Please review.

[garyschulte]

LGTM, minor nit about the the openjdk install source

[garyschulte]

FYI, testling locally I am getting
Exception in thread "main" java.lang.UnsatisfiedLinkError: no constantineeip196 in java.library.path: ...

[NickSneo]

Which OS are you testing this in?
I assume first you ran the ./build.sh and then the test files?

I tested in Mac and Linux x86_64, working fine for me

[garyschulte]

I am testing by integrating into besu on Darwin aarch64, when I build I am seeing the libs getting embedded in the jar inlib/{arch} rather than {arch}. The 0.9.4 build shows the same for the x86_64 libs.

Perhaps there is a classpath difference / expectation in besu-native/constantine that allows it to find the libs, but that same native classpath isn't in besu (since besu is using the jar dep instead of a filesystem build artifact). Looking into it now

@garyschulte I haven't changed anything for linux x86_64 but seems the pipeline is failing due to -
/tmp/choosenim-0.8.5_linux_amd64: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /tmp/choosenim-0.8.5_linux_amd64)
Do you have any idea about this?

Edit: Updated Ubuntu to 22.04 for linux x86_64 pipeline, fixed the problem with GLIBC_2.34

@garyschulte Pipeline for Mac Arm is failing due to -

We can add go, it builds fine locally. It is just the packaging that is presenting a problem for me at the moment

[NickSneo]

@garyschulte Pipelines are passing now.

Converting to JNA does seem to include a little overhead for the first call to the library, but subsequent performance is essentially identical:

The weird requirement about darwin vs linux shared library location notwithstanding, lets MERGE this and we can sort out that minor oddity in a subsequent PR 👍
