getFlag() returns true when the property is equal, ignoring case, to the
string "true", not just "true"; "TrUe" also means true.

This commit introduces a Nullness enum with related utility methods
in order to detect if a type usage, a field, a method return type or a
parameter is unspecified, nullable or not null.
JSpecify annotations are fully supported, as well as Kotlin null safety
and `@Nullable` annotations regardless of their package (from Spring,
JSR-305 or Jakarta set of annotations for example).

In ClassUtils.forName(), we originally delegated to
ClassLoader.loadClass(), which does not support loading classes from
binary names for arrays (such as "[[I" for "int[][]" or
"[Ljava.lang.String;" for "String[]"); whereas, Class.forName() does
support binary names for arrays.
However, in Spring Framework 5.1.1 we switched from using
ClassLoader.loadClass() to Class.forName() in ClassUtils.forName() (see
gh-21867), which makes our custom handling of binary names for arrays
in ClassUtils.forName() obsolete.
In light of that, this commit removes our custom binary array name
handling support from ClassUtils.forName().

This commit harmonizes how a candidate value is parsed to extract its
key and default, if any. Rather than returning {@code null} if no
default is available, `splitKeyAndValue` now consistently returns a
non-null array.
This prevents an escaped separator character to be mistakenly identified
as a placeholder in certain cases.

This commit refines KotlinDetector usages and implementation in order
to remove preliminary KotlinDetector#isKotlinReflectPresent invocations
and to ensure that KotlinDetector methods are implemented safely and
efficiently for such use case.
Closes gh-34275
For ComandLineArgs, supplying the same option multiple times with
different values is valid, and the values will be stored in a List.
This commit also updates the Javadoc for SimpleCommandLineArgsParser.
