Extract `DefaultPropertiesPropertySource` from `SpringApplication` so
that logic can be easily accessed by other classes. Specifically the
property source name and logic to move the source to the end of the
list needs to be called from several places.

Add a new `DeferredLogFactory` interface and `DeferredLogs`
implementation that can be used when a `DeferredLog` instance is needed
but the `switchOver` method should be handled elsewhere.
This interface has primarily been added so `EnvironmentPostProcessor`
classes will no longer need to implement `ApplicationEventListener`
just to switch over their logs.
Closes gh-22496
Update `OriginTrackedPropertiesLoader` so that it can support
multi-document properties files. These are similar to multi-document
YAML files but use `#---` as the separator.

Update `OriginTrackedYamlLoader` so that empty documents are filtered
from the result. Prior to this commit, our origin wrapper would confuse
the YAML processor and cause empty documents to be included in the Map
with a key of "document" and no value.
Closes gh-22493
Update value object binder support so that parameters can be annotated
with `@Name` if a specific property name should be used. Prior to this
commit is was not possible to use Java reserved words as property names.
Closes gh-22492
Prior to this commit, the application availability infrastructure
would mix the `AvailabilityState`, the `HealthIndicator` and the
`HealthGroup` concepts and would not align with the rest.
This commit auto-configures the livenessState and readinessState
health indicators with the relevant configuration properties.
Unlike other indicators, they are not enabled by default but might
be in future versions.
This also moves the `management.health.probes.enabled` property
to `management.endpoint.health.probes.enabled` since "probes" here
is not a health indicator but rather a configuration flag for the
health endpoint.
Finally, the probes auto-configuration is refined to automatically
add liveness and readiness indicators for the probes group if
they're not already present.
Closes gh-22107
