[ci-scan] Known Build Error: stackoverflowtester assert m_crawl.GetCodeInfo()->IsValid() in runtime-interpreter

## Build Information
Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1410560
Build error leg or test failing: windows x64 Checked-baseservices/exceptions/stackoverflow/stackoverflowtester/stackoverflowtester.cmd

## Error Message

```json
{
"ErrorMessage": "Thread: 4060 [0x0fdc]): m_crawl.GetCodeInfo()->IsValid()",
"ErrorPattern": "",
"BuildRetry": false,
"ExcludeConsoleLog": false
}
```

`stackoverflowtester` fails in `runtime-interpreter` (def 316) on Windows under CoreCLR interpreter mode. After a stack overflow is raised, the runtime walks the stack to unwind/report it; the `StackFrameIterator` encounters an interpreter frame whose `CodeInfo` is invalid, triggering the `m_crawl.GetCodeInfo()->IsValid()` assertion. This is an interpreter-mode stack-walker incompatibility when handling stack overflows.

**Affected pipelines (2 confirmed failing builds):**
- runtime-interpreter (def 316): windows-x64 Checked and windows-arm64 Checked — builds 1410560, 1407440

**Errors log:**

**First build it occurred:** Build 1407440 (May 4, 2026) is the earliest in the scanned window. Occurrence count in window: 2.

**Recommended action:**
- Owner: `@dotnet/coreclr-interpreter` (interpreter area)
- Root cause: `StackFrameIterator` encounters an interpreter frame during stack overflow handling where the CodeInfo is null or invalid. The interpreter needs to ensure that frames it creates have valid CodeInfo, or the stack walker needs to handle null CodeInfo gracefully in the interpreter-frame case.
- Investigate `src/coreclr/vm/stackwalk.cpp` and interpreter frame creation.
- Short-term: add `[SkipOnCoreClr("Stack overflow handling crashes under interpreter", RuntimeTestModes.InterpreterActive)]` to the `stackoverflowtester` test once this KBE issue number is known.
