Verify that modules work properly with Micronaut 3.0

[ilopmar]

We need to upgrade all modules to Micronaut 3.0 and release new major versions of them.

To do the upgrade:

• Upgrade Micronaut version in the module to Micronaut 3.0.0-M2 (or any release after it)
• Use Micronaut nullability annotations
• Switch to Jakarta annotations.
• Change javax.inject.Provider to io.micronaut.context.BeanProvider
• If the module has an RxJava dependency add a dependency on implementation 'io.projectreactor:reactor-core' and switch to it (look for RxJava2 - Reactor equivalences in Migration from RxJava2 to Reactor #5583). Public interfaces should not expose reactor types but Publisher.
• Upgrade to Gradle 7
• Upgrade to the latest version on the build plugins (currently 4.0.0) and docs (2.0.0.RC1)
• Review the annotations in this PR Allow controlling annotation inheritance with @Inherited #5643 and modify the module accordingly
• Review @Introspected classes. If the annotation is there for GraalVM, then replace it with @ReflectiveAccess. If not, just add @ReflectiveAccess/@TypeHint.
• Release a new major Milestone version of the module that targets Micronaut 3.0.x branch in core.
• When Micronaut 3.0 is released we need to upgrade the module with 3.0.0 (instead of the M or RC version) and release a new patch version targeting next Micronaut 3 patch release (theoretically 3.0.1)

Legend:

Symbol	Status
✅	Upgraded to Micronaut 3
✳️	Upgrade to Micronaut 3 in progress, waiting on some dependency
❌	Doesn't work with Micronaut 3
❓	Hasn't been tested with Micronaut 3
☑️	Not Applicable

The upgrade PRs are mostly to see the changes required for the upgrade, so that when they want to move ahead, don't need to start from scratch. PRs that are failing are marked as draft to prevent merges.

Micronaut version in the following tables is the current Micronaut version used in master branch

@micronaut-projects/core-developers after upgrading all the modules to Micronaut 3.0.0-RC1, the following still fail:

• Servlet: Upgrade to Micronaut 3.0.0-RC1 micronaut-servlet#230
• Views: Upgrade to Micronaut 3.0.0-RC1 micronaut-views#278
• RxJava2: Upgrade to Micronaut 3.0.0-RC1 micronaut-rxjava2#10
• GCP: Upgrade to Micronaut 3.0.0-RC1 micronaut-gcp#478
• Oracle Cloud: Upgrade to Micronaut 3.0.0-RC1 micronaut-oracle-cloud#241
• Jax RS: Upgrade to Micronaut 3.0.0-RC1 micronaut-jaxrs#140
• Jackson XML: Upgrade to Micronaut 3.0.0-RC1 micronaut-jackson-xml#133
• Spring: Upgrade to Micronaut 3.0.0-RC1 micronaut-spring#213

I've also upgraded Micrometer but not 100% if that was the proper fix: micronaut-projects/micronaut-micrometer#284

@ilopmar micronaut-coherence seems to be using micronautVersion = '3.0.1' already along with
Gradle 7.1, and build plugin 4.1.1
