[Known Build Error] Test_Windows_Desktop_Release_32: Test host process crashed

## Build Information
Build: https://dev.azure.com/dnceng-public/cbb18261-c48f-4abb-8651-8cdcb5474649/_build/results?buildId=1520534&view=logs&j=4f4b926f-8abe-5536-d4a9-2361289b3c74
Build error leg or test failing: Windows_Release_Desktop / Test_Windows_Desktop_Release_32 / Run Unit Tests
Pull request: https://github.com/dotnet/roslyn/pull/84575

## Error Message

```json
{
"ErrorMessage": "The active test run was aborted. Reason: Test host process crashed",
"ErrorPattern": "",
"BuildRetry": true,
"ExcludeConsoleLog": false
}
```

## Additional details

Recurring `testhost.net472.x86` crash on the `Test_Windows_Desktop_Release_32` leg (`windows.amd64.vs2026.pre.scout.open` Helix queue), not correlated with PR content — same signature (different failing test assembly each time) observed across multiple unrelated `main` builds in the same window:
- Build 1520534 (PR #84575) — crash after `Microsoft.VisualStudio.LanguageServices.LiveShare.UnitTests.ProjectsHandlerTests`
- Build 1520424 (`main`) — crash after `Microsoft.CodeAnalysis.LanguageServer.Protocol.UnitTests` started
- Build 1520169 (`main`) — same `Release_32` job failure

No crash dump is captured (`Data collector 'Blame' message: procdump.exe could not be found, please make sure that the executable is available on PATH`), so the underlying exception type can't be confirmed from the console log alone, but the pattern matches prior closed issues about 32-bit OOM crashes on this same leg: #82135, #83640.

Likely related root causes to investigate:
- x86 (32-bit) `testhost` memory pressure on `windows.amd64.vs2026.pre.scout.open` — consider further partitioning `Release_32`.
- `procdump.exe` missing from PATH on this queue image, preventing crash dump collection for diagnosis.
