[ci-scan] Skip paltest_pal_sxs_test1 on osx-arm64 (refs #128530)

[github-actions]

Reasoning

The PAL SxS test (paltest_pal_sxs_test1) consistently fails with exit code 137 (SIGKILL) on osx-arm64 Debug in the coreclr outerloop pipeline (definition 108). Exit code 137 indicates the process was killed by the OS (OOM killer or timeout). This has been persistent for over 2 weeks.

The chosen mechanism (ExcludeList in issues.targets) is the standard way to exclude individual PAL tests on specific OS/arch combinations.

Linked KBE: dotnet#128530

Match verification (from Step 4.8):

1. Same test/family: yes — exception_handling/pal_sxs/test1/paltest_pal_sxs_test1 matches KBE
2. Same failure signature: yes — exit code 137 (SIGKILL) matches KBE description
3. Same OS: yes — osx matches
4. Same architecture: yes — arm64 matches

Impact on platforms

• runtime-coreclr outerloop (def 108) / osx-arm64 Debug / OSX.26.Arm64.Open / no stress / exit code 137
