summary:

bpo-45200: GHA Address Sanitizer skips 3 slowest tests (GH-30797)

Skip the 3 slowest tests of the Address Sanitizer CI of GitHub
Actions:

* test_tools
* test_peg_generator
* test_concurrent_futures

These tests take between 5 and 20 minutes on this CI which makes this
CI job the slowest. Making this CI job faster makes the whole Python
workflow faster. These tests are run on all others CIs.

Example of Address Sanitizer output:

    10 slowest tests:
    - test_peg_generator: 17 min 33 sec
    - test_tools: 8 min 27 sec
    - test_concurrent_futures: 5 min 24 sec
    - test_zipfile: 2 min 41 sec
    - test_compileall: 2 min 21 sec
    - test_asyncio: 2 min 17 sec
    - test_gdb: 1 min 43 sec
    - test_weakref: 1 min 35 sec
    - test_pickle: 1 min 18 sec
    - test_subprocess: 1 min 12 sec

Moreover, test_concurrent_futures also seems to be affected by
bpo-45200 bug: libasan dead lock in pthread_create().
