[ubsan] Test CFI summaries globally (#206434)

Always enable report_error_type=1 and print_summary=1 for CFI tests, and
update existing tests to check for cfi-bad-type. This allows us to
verify summary output comprehensively across the test suite.

This is a prerequisite for the change to the UBSan summary for CFI in
https://github.com/llvm/llvm-project/pull/203341.
