RFR: 8321219: runtime/jni/FastGetField: assert(is_interpreted_frame()) failed: interpreted frame expected [v2]

[Serguei Spitsyn]

> This is a trivial fix for a regression caused by:
>  [8308614](https://bugs.openjdk.org/browse/JDK-8308614) Enabling JVMTI ClassLoad event slows down vthread creation by factor 10
> 
> The fix of 8308614 just triggered a known issue:
>   [8316283](https://bugs.openjdk.org/browse/JDK-8316283) field watch events are not always posted with -Xcomp option
>   
> The fix is just a work around with the extra checks with the `JvmtiExport::should_post_field_access()` and `JvmtiExport::should_post_field_modification()`.
> 
> Testing:
> - The test `runtime/jni/FastGetField/FastGetField.java` does not fail anymore with this fix
> - In progress: Test with tiers 1-6
