[LowerTypeTests] Add debug info to jump table entries (#194493)

[LowerTypeTests] Add debug info to jump table entries (#192736)

When Control Flow Integrity (CFI) is enabled, jump tables are used to
redirect indirect calls. Previously, these jump table entries lacked
debug information, making it difficult for profilers and debuggers to
attribute execution time correctly.

Now stack trace, when stopped on jump table entry will looks like this:
```
#0: c::c() (.cfi_jt) at sanitizer/ubsan_interface.h:0:0
#1: __ubsan_check_cfi_icall_jt at sanitizer/ubsan_interface.h:0
```

Following up on previous attempts #192736 and #193670, this PR is
essentially #192736 but with the `(.cfi_jt)` and
`__ubsan_check_cfi_icall_jt`
frames swapped. While the specific order of `__ubsan_check_cfi_icall_jt`
isn't strictly necessary, swapping them helps maintain existing
diagnostics
behavior.
Additionally, the diagnostics must remove `ubsan_interface.h` to allow
for a fallback to printing the module name.
See "Commits" tab for details.
