Create static lib artifact for arithmetic

[garyschulte]

In support of graal static compilation, besu-native needs to provide precompiles and other native code as static libraries, corresponding header files and provide graal sdk java classes.

Arithmetic is used by besu for the mod_exp precompile.

Acceptance criteria:

• creation of arithmetic--static.jar which includes
  • .a libraries for each arithmetic lib
  • .h header files for each arithmetic lib
  • LibArithmetic*Graal.java counterparts for the existing jna libs
• ci workflow changes to ensure the arithmetic--static.jar artifacts are built and included in releases
