[vm/ffi] Implement FFI callbacks on AOT for ELF and Asm snapshots (excl. blobs).

To do this, we add writable data sections (currently uninitialzed) to ELF and Asm snapshots
and allow Instructions to have patchable relocations against (the start of) these sections.

Issue https://github.com/dart-lang/sdk/issues/37295 (see also for design & discussion).
