[release/8.0] Events for IL methods without IL headers (#90844)

* Events for IL methods without IL headers

Dynamically generated methods like UnsafeAccessor
functions are marked as IL, but don't contain an IL
header. The lack of header is an indication the IL must
be generated at runtime.

* Debugger check for no IL header

* Update src/coreclr/debug/daccess/stack.cpp
