Improve debuggability for kernel registration issues

[larryliu0820]

🚀 The feature, motivation and pitch

We need to enable developers to figure out issues like the following on their own:

E 00:00:00.032942 executorch:operator_registry.cpp:86] Re-registering aten::sym_size.int, from /data/users/larryliu/fbsource/buck-out/v2/gen/fbsource/cfdc20bd56300721/arvr/libraries/wristband/tsn/transformers/__TorchstreamTransformerTest__/./__TorchstreamTransformerTest__shared_libs_symlink_tree/libexecutorc$
E 00:00:00.033022 executorch:operator_registry.cpp:87] key: (null), is_fallback: true
F 00:00:00.033033 executorch:operator_registry.cpp:111] In function register_kernels(), assert failed (false): Kernel registration failed with error 18, see error log for details.

This is important both internally and in OSS.
