Test failure Loader/classloader/explicitlayout/NestedStructs/case05/case05.sh

[VincentBu]

Edit there are two separate issues here all on the Linux x64 LLVM AOT lane:

1. The new tests from [Mono] Fix support for nested structs with explicit layout #61467

Loader/classloader/explicitlayout/NestedStructs/case05/case05.sh
Loader/classloader/explicitlayout/NestedStructs/case04/case04.sh
Loader/classloader/explicitlayout/NestedStructs/case03/case03.sh
Loader/classloader/explicitlayout/NestedStructs/case01/case01.sh

2. The new test from [mono] Fix StackTrace from a dim and Vtable offsets for static interface method #60770

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

* Assertion at /__w/1/s/src/mono/mono/metadata/class-init.c:1906, condition `m_class_is_fields_inited (embedded_class)' not met

It's the LLVM AOT lane. which makes sense - we may have only loaded some AOT image info about the nested class, not necessarilly fully initialized it.

@vargaz @thaystg the new test from #60770 is failing on the AOT lane - looks like context->method_inst is non-NULL but garbage:

Look at collect_ginst_images in frame 6
