Since the move to JUnit 5, a number of tests were failing on Windows.
The majority were failing due to open file handles preventing the
clean up of the tests' temporary directory. This commit addresses
these failures by updating the tests to close JarFiles, InputStreams,
OutputStreams etc.
A change has also been made to CachingOperationInvokerTests to make
a flakey test more robust. Due to System.currentTimeMillis() being
less precise on Windows than it is on *nix platforms, the test could
fail as it would not sleep for long enough for the TTL period to have
expired.
Split the JUnit 5 `OutputCapture` class into separate `OutputExtension`
and `CapturedOutput` classes. The JUnit 5 callback methods are now
contained only in the `OutputExtension` class so no longer pollute the
public API that users will interact with.
The `CapturedOutput` class has also been updated to capture System.err
and System.out separately to allow distinct assertions if required.

Refactor `Autotime` from a properties object to an interface and
change the existing metric recording implementations. The `AutoTimer`
interface is a general purpose callback that can be applied to a
`Timer.Builder` to configure it. Autotime properties are now located
in `spring-boot-actuator-autoconfigure` and have become an
implementation of the interface.

This commit merges the conditions for determining if an endpoint is
available in a single condition, deprecating
`ConditionalOnEnabledEndpoint` in the process.
Closes gh-16169
Prior to this commit, the audit auto-configuration provided
an `InMemoryAuditEventRepository` bean. This commit changes the auto-config
so that an `AuditEventRepository` is not provided and instead the auto-config
is conditional on the presence of a `AuditEventRepository` bean. This is done
to encourage the use of a custom implementation of `AuditEventRepository`
since the in-memory one is quite limited and not suitable for production.
A flag is available if the auto-configuration needs to be turned off even
in the presence of a bean.
Closes gh-16110
