Simplify HTTP client configuration properties by sharing common
settings for both blocking and reactive clients.
The `ClientHttpRequestFactorySettings` and `ClientHttpConnectorSettings`
have been merged to a single `HttpClientSettings` class. Properties
to configure common settings are available under:
`spring.http.clients`
Blocking and reactive settings have been moved to
`spring.http.clients.blocking` and `spring.http.clients.reactive`. With
currently only the factory/connector being configurable.
HTTP Service Client properties have also been rationalized under a
`spring.http.serviceclient.<group-name>`. Support for properties that
apply to all service clients and all Rest/Web Clients have been removed.
Support for `ApiVerionInserter` beans has also been removed in favor of
configuring the service group or builders directly.

Refactor `PropertyMapper` so that it no longer calls adapter or
predicate methods by default when the source value is `null`. This
effectively makes all default calls the same as using
`alwaysWhenNotNull` in the previous generation of the code.
For the limited times when you do need to deal with `null` values, the
new `always()` method can be used.
For example,
map.from(source::method).to(destination::method);
Will not call `destination.method(...)` if `source.method()` returns
`null`.
Where as:
map.from(source::method).always().to(destination::method);
Will call `destination.method(null)` if `source.method()` returns
`null`.
This update provides clearer semantics for the API and allows for better
JSpecify nullability annotations. It has also simplified much of our
existing property mapper code.

Update service client configuration so that properties are always
applied when present. Any settings and factory/connector beans that
are present are now only used as fallbacks.
Fixes gh-46915
Refactor `HttpServiceClientAutoConfiguration` and
`ReactiveHttpServiceClientAutoConfiguration` to support scanning for
`@HttpServiceClient` annotated interfaces.
