Cleanup - Removes the CLI option "no-bpf-jit"

[Lichtso]

Problem

This option is useless in production and for debugging the validator is mostly build from sources. It is routed through the validator code via multiple obscure techniques such as registering multiple versions of the same built-in program. It should be removed because it stands in the way of unifying all built-in programs in one place.

Summary of Changes

• Removes the CLI argument "no-bpf-jit".
• Removes its plumbering through out the validator code base.
• Removes the with_jit variants of the bpf_loader programs.
• Removes the to_builtin!() macro.

[dmakarov]

Why was it necessary to remove no-bpf-jit option? Running rbpf-cli doesn't work on Mac M1/M2 without interpreted mode of execution.

[Lichtso]

The Interpreter is still the fallback which is automatically used when the JIT is not available.
