[GR-69713] Adopt JVMCI separation from AnnotatedElement.

[graalvmbot]

This PR migrates all usages of AnnotatedElement APIs, such as getAnnotation, getAnnotations, getDeclaredAnnotations, and parameter annotation retrieval, from the JVMCI type hierarchy and user code. The APIs in AnnotationValueSupport and AnnotationUtil centered around AnnotationValue and now provide equivalent functionality, better aligned to both HotSpot and non-HotSpot environments. This resolves the major design limitation where reflection-based annotation APIs only worked reliably when JVMCI was running on HotSpot.

In compiler code, annotation queries use AnnotationValueSupport and are thus limited to annotations represented as AnnotationValue objects. Annotation elements are accessed by name (e.g. annotation.getInt("count")).

In SVM code, annotation queries make use of AnnotationUtil to obtain Annotation objects and thus have access to typed element accessors (e.g. annotation.count()).
