This commit enhances the `ScheduledAnnotationBeanPostProcessor` to
instrument `@Scheduled` methods declared on beans. This will create
`"tasks.scheduled.execution"` observations for each execution of a
scheduled method. This supports both blocking and reactive variants.
By default, observations are no-ops; developers must configure the
current `ObservationRegistry` on the `ScheduledTaskRegistrar` by using a
`SchedulingConfigurer`.
Closes gh-29883
This commit changes the Java system property used to
control PreComputeFieldFeature verbose logging from
spring.aot.precompute to spring.native.precompute.log
in order to clarify its purpose and avoid confusion
with AOT processing of JVM bytecode or Java sources.

This commit overhauls the TestExecutionListener for Micrometer's
ObservationRegistry that was introduced in the previous commit.
Specifically, this commit:
- Renames the listener to MicrometerObservationRegistryTestExecutionListener
since the use of a ThreadLocal is an implementation detail that may
change over time.
- Makes the listener package-private instead of public in order to
allow the team greater flexibility in evolving this feature.
- Eagerly loads the ObservationThreadLocalAccessor class and verifies
that it has a getObservationRegistry() method to ensure that the
listener is properly skipped when SpringFactoriesLoader attempts to
load it, if Micrometer 1.10.8+ is not on the classpath.
- Switches the listener's automatic registration order to 2500 in order
to register it after the DependencyInjectionTestExecutionListener.
- Only tracks the previous ObservationRegistry in beforeTestMethod() if
the test's ApplicationContext contains an ObservationRegistry bean.
- Properly removes the TestContext attribute for the previous
ObservationRegistry in afterTestMethod().
- Introduces DEBUG logging for diagnostics.
- Adds an entry in the Javadoc for TestExecutionListener as well as in
the Testing chapter in the reference manual.
Closes gh-30658
Prior to this commit, there was no way to specify the
ObservationRegistry that is registered in the given test's
ApplicationContext as the one that should be used by Micrometer's
ObservationThreadLocalAccessor for context propagation.
This commit introduces a TestExecutionListener for Micrometer's
ObservationRegistry in the Spring TestContext Framework. Specifically,
this listener obtains the ObservationRegistry registered in the test's
ApplicationContext, stores it in ObservationThreadLocalAccessor for the
duration of each test method execution, and restores the original
ObservationRegistry in ObservationThreadLocalAccessor after each test.
