Prior to this commit, the resource hints for AOT applications would
generate JSON metadata with `java.util.regex.Pattern`, like:
```
{
"resources": {
"includes": [
{
"pattern": "\\Qbanner.txt\\E"
}
]
}
}
```
This regexp feature, as well as "includes" and "excludes" are not supported
anymore with the new metadata format. This commit removes the pattern
format which is now replaced by a "glob" format.
"globs" should only contain "*" (zero or more characters in a path
segment) or "**" (zero or more path segments).
Some instances of resource hint registration should be migrated as a
result.
For example, "/files/*.ext" matched both "/files/a.ext" and
"/files/folder/b.txt" in the past. The new behavior matches only the
former, unless the "/files/**/*.ext" glob pattern is used.
This commit also removes the "excludes" support, which was not widely
used and very often could lead to subtle behavior.

Prior to this commit, Spring would create directly
`SimpleMetadataReaderFactory` instances or would manually create
`CachingMetadataReaderFactory` which extend
`SimpleMetadataReaderFactory`. This would prevent usage of the new
`ClassFileMetadataReaderFactory` in our internal codebase.
This commit replaces manual instantiations with calls to
`MetadataReaderFactory` factory methods and makes
`CachingMetadataReaderFactory` delegate to another factory created with
the same factory methods.
This allows internal usage of `ClassFileMetadataReaderFactory`
internally.
Closes gh-33616
Prior to this commit, Spring Framework would allow two ways of getting
class metadata:
* `StandardClassMetadata`, using the Java reflection API
* `SimpleMetadataReaderFactory`, using ASM to read the class bytecode
This commit adds a new implementation for this feature, this time using
the new `ClassFile` API which is taken out of preview in Java 24.

Before this commit, in Spring Framework 6.2, Kotlin value class
unboxing was done at CoroutinesUtils level, which is a good fit
for InvocableHandlerMethod use case, but not for other ones like
AopUtils.
This commit moves such unboxing to InvocableHandlerMethod in
order to keep the HTTP response body support while fixing other
regressions.
Closes gh-33943
This commit introduces a `@CheckReturnValue` annotation,
inspired from org.jetbrains.annotations.CheckReturnValue,
that specifies that the method return value must be used.

Update `PathMatchingResourcePatternResolver` so that in addition to
searching the `java.class.path` system property for classpath enties,
it also searches the `MANIFEST.MF` files from within those jars.
Prior to this commit, the `addClassPathManifestEntries()` method
expected that the JVM had added `Class-Path` manifest entries to the
`java.class.path` system property, however, this did not always happen.
The updated code now performs a deep search by loading `MANIFEST.MF`
files from jars discovered from the system property. To deal with
potential performance issue, loaded results are also now cached.
The updated code has been tested with Spring Boot 3.3 jars extracted
using `java -Djarmode=tools`.
See gh-33705
