[GR-70912] Replace AnnotatedElement usages with AnnotatedValueSupport in the compiler.

[graalvmbot]

This PR replaces usages of AnnotatedElement methods in the Graal compiler with methods in AnnotationValueSupport. This was mostly done with IntelliJ's support for structural replacement (Edit -> Find -> Replace Structurally...).

Inherent in this change is the switch to using AnnotationValue objects instead of Annotation objects. Given that all uses of annotations in the compiler are only in a context where full reflection is supported (e.g. jargraal), it would be possible to use the AnnotationValueParser but still return Annotation objects. This would involve moving com.oracle.svm.hosted.annotation.SubstrateAnnotationExtractor#toAnnotation to AnnotationValueSupport. However, that means we'd need to export java.base/sun.reflect.annotation to jdk.graal.compiler (complicating all jargraal-like launchers). I don't think that's worth it given the limited use of annotations in the compiler.

[Summary of the PR]

Key Changes:

• Replaces usages of AnnotatedElement methods in the compiler with AnnotationValueSupport methods, as a prerequisite for GR-69713. All annotation lookups now rely on the new abstraction over annotation parsing and values.
• Migrates all annotation work in the Graal compiler to use AnnotationValue (and associated APIs), instead of Java reflection-based Annotation objects, ensuring proper separation and native-image compatibility.
• Implements a new verifier test (VerifyAnnotatedElementUsage) to ensure direct calls to AnnotatedElement methods on JVMCI types no longer occur within the compiler.
• Updates various method and field annotation lookups throughout Graal and its test infrastructure (e.g., plugin registration, snippet handling, bridge method annotation logic) to use the new AnnotationValueSupport methods.
• Refactors the annotation cache strategy and adds logic to support caching of resolved annotation types in a native-image-compatible way.
• Updates bridge method annotation utilities to properly forward annotation lookups through AnnotationValueSupport.
• Extends and updates the AnnotationValue API to support strongly-typed element value extraction, including enums and primitives.
• Updates related JVMCI and test classes to ensure they now use the new annotations infrastructure.
• Adds more robust caching and lookups for resolved annotation types and annotation values.
• Adds a build-time-only test (VerifyAnnotatedElementUsage) to fail if banned usages are reintroduced going forward.
• Performs minor cleanups and clarifies JavaDoc and usage for the new annotation mechanisms.
