[ubsan] Report specific CFI checks in UBSan summaries (#213224)

Instead of reporting generic `cfi-bad-type` in UBSan summaries for CFI
failures, report the specific CFI check kind (e.g., `cfi-vcall`,
`cfi-nvcall`, `cfi-icall`, `cfi-mfcall`, `cfi-derived-cast`,
`cfi-unrelated-cast`).

This is done by splitting CFIBadType into specific error types in
ubsan_checks.inc, and updating the handlers to report the appropriate
ErrorType based on the check kind. The suppression flag name for all of
them remains `cfi` to maintain backward compatibility.

Also replaces cfi-bad-type expectations in the existing tests.
