Update `SpringApplicationShutdownHook` so the underlying set of
`Runnable` instances are stored in a `LinkedHashSet` rather than
a `Collections.newSetFromMap(new IdentityHashMap<>())`. This insures
that shutdown hooks are run in the order that they are added.

Before this commit, only a single ResourceHandlerRegistrationCustomizer
was invoked. This commit adds functionality to have more
than one ResourceHandlerRegistrationCustomizers
See gh-43494
Add a new `TestcontainersStartup.start` static method and update the
existing start methods so that `Startable.start()` is only called when
the container is not already running.
Prior to this commit, we assumed that `Startable.start()` calls were
idempotent and could be safely made multiple times. Whilst this appears
to be true for stock `GenericContainer` based startables, users may have
their own `start()` method that does not expect to be called multiple
times.
The implemented detection logic will not be applied if a `Startable`
is not also a `Container`. In these cases, the implementation will need
to deal directly with multiple `start()` calls.

Prior to this change, the failure analysis for an invalid
configuration property value filtered out the configuration property
sources property source. This property source contains a "duplicate"
of all of the environment's other property sources but with
configuration property support (such as relaxed/fuzzy matching of
environment variables). This was done to prevent the reporting of
duplicates when a property was found in both the configuration
property sources property source and the "normal" property sources.
An unwanted side-effect of this was that fuzzy matching of
environment variables was lost so the origin of
com.example.some-property would be found in the environment variable
was COM_EXAMPLE_SOME_PROPERTY but would not be found if it was
COM_EXAMPLE_SOMEPROPERTY.
This commit addresses this side-effect by no longer filtering out
the configuration property sources property source. To then
prevent duplicates from being reported in the analysis, it instead
deduplicates things based on the origin of each property that's
found in the environment's property sources.
Fixes gh-43380
