[ci-scan] Interpreter assert SetInterpreterCode: m_interpreterCode != INTERPRETER_CODE_POISON (method.hpp:1992) crashes test hos [Content truncated due to length]

## Build Information
Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1588973
Build error leg or test failing: osx-arm64 Release NoDynamicCodeCompiled - Microsoft.Extensions.Options.SourceGeneration.Tests

KBE authoring guidance (ci-failure-scan)

- `Error Details` is for readers. Paste the full exception, stack trace, or build error excerpt so the failure is understandable without opening the raw log.
- Build Analysis parses only the single JSON block under `Error Message`.
- `ErrorMessage` is a case-sensitive ordinal `String.Contains` substring copied verbatim from the failing log.
- Set `BuildRetry` to `true` only for a clear infrastructure retry case. `ExcludeConsoleLog` disables Helix console-log scanning.

## Error Details

```
Starting: Microsoft.Extensions.Options.SourceGeneration.Tests (parallel test collections = on [8 threads], stop on fail = off)
ASSERT FAILED
Expression: dac_cast(m_interpreterCode) != INTERPRETER_CODE_POISON
Location: /Users/runner/work/1/s/src/coreclr/vm/method.hpp:1992
Function: SetInterpreterCode
Process: 43897
./RunTests.sh: line 177: 43897 Trace/BPT trap: 5 "$RUNTIME_PATH/dotnet" exec ... xunit.console.dll ...
----- end ----- exit code 133 ----------------------------------------------------------
exit code 133 means SIGTRAP Breakpoint hit. Core dumped.
```

The interpreter runtime (`runtime-libraries-interpreter`, `NoDynamicCodeCompiled` leg) aborts with a `SetInterpreterCode` assertion (`m_interpreterCode` is `INTERPRETER_CODE_POISON`) at `src/coreclr/vm/method.hpp:1992`, killing the test host with SIGTRAP (exit code 133). It is not tied to a single test: it reproduced in build 1588973 (source, `Microsoft.Extensions.Options.SourceGeneration.Tests`) and follow-up build 1592661 (`System.Linq.Parallel.Tests`), i.e. whichever suite happens to exercise the poisoned interpreter method first.

Start with the assertion in src/coreclr/vm/method.hpp:1992 and the SetInterpreterCode failure in the reported logs. Reproduce the osx-arm64 Release NoDynamicCodeCompiled leg, then compare the Microsoft.Extensions.Options.SourceGeneration.Tests and System.Linq.Parallel.Tests failures, along with the follow-up build involving Microsoft.Extensions.Configuration.Binder.SourceGeneration.Tests. Done means identifying and fixing the poisoned interpreter state without disabling tests, with the affected interpreter leg passing.
