LibJIT: Integrate GDB JIT Interface with ELF builders
Provide a function to create an ELF image in a format GDB expects. Outside of ELF platforms this image doesn't make much sense, and in MacOS a Mach-O memory image is required: see https://chromium.googlesource.com/v8/v8.git/+/refs/heads/main/src/diagnostics/gdb-jit.cc#1802 Since GDB requires active runtime addresses for the code, copying the generated code into the image will not help. Instead, `build_gdb_image` writes the runtime addresses of the code into a NOBITS `.text` section.
