fix: injectivity theorems for more prelude inductives (#6826)
This PR adds injectivity theorems for inductives that did not get them
automatically (because they are defined too early) but also not yet
manuall later.

It also adds a test case to notice when new ones fall through.o

It does not add them for clearly meta-programming related types that are
not yet defined in `Init/Core.lean`, and uses `#guard_msgs` as an
allowlist.
