codegen: restructure, remove recursion (JuliaLang#25984)

also provides support for using a different code_native format,
as a fallback, later we'll want to make this more configurable

there are now several primary interfaces to native code:
 - codegen: mostly internal, support for translating IR to LLVM
 - jitlayers: manages runtime codegen results and executable memory
 - aotcompile: support for managing external code output
 - disasm: pretty-printer for code objects
 - debuginfo: tracking for unwind info

also removes the global type caches and
move all codegen pass handling to aotcompile.cpp
