Fixes gh-160334.

Collapsed profiling output uses bare special-frame names such as <GC> and <unreadable frame> when no file or line information is available. Update the integration test to accept that established format instead of requiring every stack part to contain a colon.

The current assertion fails deterministically for a collector fed an unreadable frame; the focused test and the full sampling-profiler integration module pass with this change.

Tests:

• PCbuild\\build.bat -d -p x64 -M -q
• PCbuild\\amd64\\python_d.exe -m test -v -m test_sampling_with_collapsed_export test_profiling.test_sampling_profiler.test_integration
• PCbuild\\amd64\\python_d.exe -m test -v test_profiling.test_sampling_profiler.test_integration (21 passed, 1 skipped)
• PCbuild\\amd64\\python_d.exe Tools\\patchcheck\\patchcheck.py

AI assistance was used to investigate the test failure and prepare this change. I reviewed the collector output and the test results before opening this PR.

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

Sorry, @raman118 and @vstinner, I could not cleanly backport this to 3.14 due to a conflict.

Lib/test/test_profiling/test_sampling_profiler/test_integration.py doesn't exist in the 3.14 branch: it's not impacted.
