Update the proxy used in `AnnotatedElementUtils.forAnnotations` so
that it returns a cloned array for calls to `getDeclaredAnnotations`
or `getAnnotations`. This matches the behavior of standard JDK
`AnnotatedElement` implementations.

Namespace handlers are mapped based on the canonical names for XML
namespaces which in Spring do not use "https" as the scheme.
See gh-22617 gh-22622 gh-22635
Refine the element filtering performed by `AnnotationsScanner` to also
cover `org.springframework.util` and most `com.sun` classes which turn
out to be referenced quite frequently and which we know contain no
useful annotations.

Add a cache to `BridgeMethodResolver` to help with repeated calls to
resolve the same methods. Since bridge method resolution can be somewhat
expensive (especially when resolving generics), and the number of bridge
methods is quite small, a cache generally helps.
This commit also simplifies the code a little by calling `doWithMethods`
directly rather than relying on `ReflectionUtils.getAllDeclaredMethods`
to do so. The methods list is now always created, but we save the list
creation that `getAllDeclaredMethods` used to do.
Closes gh-22579
Add an early exit to `StringUtils.cleanPath` to save array creating and
string concatenation. With a typical Spring application, the `cleanPath`
method can be called over 600 times, often with a path constructed by
a `ClassPathResource` that is likely to already be clean.
Closes gh-22568
Update `ConcurrentReferenceHashMap` to make some methods more inline
friendly, and to manually inline a few others. These minor optimizations
don't make a great deal of difference for most applications, but seem
worthwhile since we use `ConcurrentReferenceHashMap` for many internal
caches.
Closes gh-22566
Update `ConfigurationClassParser` to skip `java.lang.annotation` types
which were often processed but would never provide useful results. Also
use a single shared immutable `SourceClass` instance to represent
`Object.class`.
Closes gh-22563
Migrate all possible `AnnotationUtils` and `AnnotatedElementUtils`
method to the `MergedAnnotation` API, verify results against the old
implementations.
All migrated methods now call both the new API and the old version and
ensure that the same results or exceptions are raised. A full build of
both Spring Framework and Spring Boot has been executed to ensure, as
much as possible, that the migration does not cause unexpected
regressions.
