This commit introduces the RestClient, a synchronous HTTP client that
offers an API similar to WebClient, using the same infrastructure (i.e.
request factory, error handler, interceptors, etc) as RestTemplate.

Extract the default logic for resolving the name of an @Valid
parameter into an ObjectNameResolver, and use it when there isn't
one configured.

To handle method validation errors in ResponseEntityExceptionHandler,
MethodValidationException and associated types should not depend on
Bean Validation. To that effect:
1. MethodValidationResult and ParameterValidationResult no longer make
the underlying ConstraintViolation set available, and instead expose
only the adapted validation errors (MessageSourceResolvable, Errors),
analogous to what SpringValidatorAdapter does. And likewise
MethodValidationException no longer extends ConstraintViolationException.
2. MethodValidationPostProcessor has a new property
adaptConstraintViolations to decide whether to simply raise
ConstraintViolationException, or otherwise to adapt the ConstraintViolations
and raise MethodValidationException instead, with the former is the default
for compatibility.
3. As a result, the MethodValidator contract can now expose methods that
return MethodValidationResult, which provided more flexibility for handling,
and it allows MethodValidationAdapter to implement MethodValidator directly.
4. Update Javadoc in method validation classes to reflect this shift, and
use terminology consistent with Spring validation in classes without an
explicit dependency on Bean Validation.

- Update method order
- Do not automatically create MessageSource arguments in
WebExchangeBindException constructor as they're more likely to be
created via getDetailMessageArguments with MessageSource passed in.
See gh-30644
Remove throwIfViolationsPresent and replace with static factory
methods on MethodValidationException taking MethodValidationResult,
which makes handling more explicit and allows choice of what
exception to raise.
Update MethodValidationResult to expose the target, the method, and
forReturnValue flag, so the code handling an exception will have
access to all details.
See gh-30644
By default, the JDK HttpClient's HttpRequest does not allow Connection,
Content-Length, Expect, Host, or Upgrade headers to be set, but this can
be overriden with the `jdk.httpclient.allowRestrictedHeaders` system
property.

This commit adds support for WildcardType bounds resolution,
commonly seen in Kotlin due to declaration-site variance,
but also possible in Java even if less common.
