RFR: 8309399: JVMTI spec needs to clarify when OPAQUE_FRAME is thrown for reasons other than a native method [v7]

[Serguei Spitsyn]

> It was decided in a local discussion with Chris and Alan to update the JVMTI spec to make descriptions/clarifications of some `JVMTI_ERROR_OPAQUE_FRAME` cases more consistent.
> This impacts the following JVMTI spec sections:
>   - `PopFrame`
>   - `NotifyFramePop`
>   - `ForceEarlyReturn<Type>`
>   - `GetLocal<Type>`
>   - `SetLocal<Type>`
>   - general description of the `JVMTI_ERROR_OPAQUE_FRAME` error code
>   
> A related CSR is going to be filed for this spec update.
> 
> Testing:
>  - it is N/A in general but mach5 tiers 1-3 will be run to be completely safe
