[ci-scan] Build break: Mono AOT compile of JIT.Generics_ro fails with recursive/invalid generic instantiation on linux-x64 MiniF [Content truncated due to length]

## Build Information
Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1558665
Build error leg or test failing: linux-x64 Release AllSubsets_Mono_MiniFullAot_RuntimeTests minifullaot - AOT compile CoreCLR tests (JIT.Generics_ro.dll)

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

The Mono AOT compile step (`aot-compile.proj`) fails while precompiling `JIT.Generics_ro.dll` on the `linux-x64 Release AllSubsets_Mono_MiniFullAot_RuntimeTests minifullaot` leg of `runtime-extra-platforms` (definition 154). The corerun-driven AOT pass emits over a thousand `Failed to load methodspec` errors rooted in recursive/invalid generic instantiations, then the MSBuild `Exec` reports failure:

```
EXEC : Failed to load methodspec 0x2b0003fa due to Could not find method 'VerifyA0A1A2A3NotInlinedGenericStatic' due to a type load error : Could not set up parent class, due to: Generic Type Definition failed to init, due to: Could not set up parent class, due to: Generic Type Definition failed to init, due to: Recursive type definition detected JitTest_Generics_Coverage_chaos65204782cs.A0A1`1 ... [/__w/1/s/src/mono/msbuild/aot-compile.proj]
/__w/1/s/src/mono/msbuild/aot-compile.proj(19,9): error MSB3077: The command "/__w/1/s/artifacts/tests/coreclr/linux.x64.Release/Tests/Core_Root/corerun /__w/1/s/artifacts/tests/coreclr/linux.x64.Release/JIT/Generics/JIT.Generics_ro/JIT.Generics_ro.dll" exited with return value 0, but errors were detected during execution. ExitCode was set to -1.
1154 Error(s)
Build failed with exit code 1. Check errors above.
```

The failure is persistent: it reproduces across the entire scanned ~25-build window (all builds `failed`) and in the follow-up build 1560207. True origin likely predates the scanned window.

## Error Message

```json
{
"ErrorMessage": "JIT/Generics/JIT.Generics_ro/JIT.Generics_ro.dll\" exited with return value 0, but errors were detected during execution. ExitCode was set to -1.",

Start with the linked Azure DevOps logs and src/mono/msbuild/aot-compile.proj, focusing on the linux-x64 minifullaot failure for JIT.Generics_ro/JIT.Generics_ro.dll. Trace the recursive generic-instantiation and Failed to load methodspec errors in the AOT compile step, then reproduce the failure; done means the affected AOT build completes without these errors.
