This commit introduces tests which serve as "regression tests" for the
behavior of PathMatchingResourcePatternResolver in Spring Framework
5.3.x with regard to URL-encoding and Unicode normalization of resource
paths.
Specifically, the new tests demonstrate that resource paths do NOT need
to be decoded or normalized in 5.3.x.

Spring Framework 5.0 introduced a regression in ASM-based annotation
processing. Specifically, nested annotations were no longer supported,
and component scanning resulted in an exception if a candidate
component was annotated with an annotation that contained nested
annotations.
This commit fixes this regression by introducing special handling in
AnnotationTypeMapping that supports extracting values from objects of
type TypeMappedAnnotation when necessary.
Closes gh-24375
