190n 97a530d832 [publish images] [BAPI-2103] use gdb and bun.report code to print stack traces upon crash in CI (#21143) 
### What does this PR do?

Closes #13012

On Linux, when any Bun process spawned by `runner.node.mjs` crashes, we
run GDB in batch mode to print a backtrace from the core file.

And on all platforms, we run a mini `bun.report` server which collects
crashes reported by any Bun process executed during the tests, and after
each test `runner.node.mjs` fetches and prints any new crashes from the
server.

I used GDB instead of LLDB (as the branch name suggests) because it
seems to produce more useful stack traces with musl libc.

- [x] on linux, use gdb to print from core dump of main bun process
crashed
- [x] on linux, use gdb to print from all new core dumps (so including
bun subprocesses spawned by the test that crashed)
- [x] on all platforms, use a mini bun.report server to print a
self-reported trace (depends on oven-sh/bun.report#15; for now our
package.json points to a commit on the branch of that repo)
- [x] fix trying to fetch stack traces too early on windows
- [x] use output groups so the traces show up alongside the log for the
specific test instead of having to find it in the logs from the entire
run
- [x] get oven-sh/bun.report#15 merged, and point to a bun.report commit
on the main branch instead of the PR branch in package.json

### How did you verify your code works?

Manually, and in CI with a crashing test.
