Add external function registry support to gandiva. JSON based function registry can be used for describing the function metadata, and LLVM bitcode can be automatically loaded as pre-compiled external functions. ### Rationale for this change This PR tries to enhance Gandiva by supporting external function registry, so that developers can author third party functions without modifying Gandiva's core codebase. See https://github.com/apache/arrow/issues/37753 for more details. ### What changes are included in this PR? This PR implements basic support of external function registry. It primarily implements two parts to make it work: 1) define a JSON based function registry format to describe the function metadata, and support loading and parsing such JSON based function registry files from some directory 2) automatically load and parse LLVM bitcode from files, so that third party pre-compiled functions can be integrated via LLVM bitcode The overall flow looks like this: <img width="2750" alt="external-func-registry" src="https://github.com/apache/arrow/assets/27754/8a961d01-aba0-45b4-9e5e-b46245f01524";> ### Are these changes tested?
