Use explicit library loading rather than relying on JNA

[garyschulte]

Description

JNA's Native.register() function is convenient and tidy, but presents problems on platforms that can have non-standard OS_ARCH names. For example, some versions of linux might report arch as linux-x86-64 where others might report that same arch as linux-gnu-x86_64. This causes problems for packaging and auto-loading native libraries across different distributions and operating systems.

besu-native lib loading needs to be more explicit and opinionated in order to ensure native library implementations are available for all supported platforms.

The c-kzg-4844 java wrapper has fairly robust native lib loading. Using a similar strategy would not only be more robust than JNA, but it would also conform the native lib loading behavior across besu's native lib providers.
