Create quarkus-smallrye-jwt-build extension

[sberyozkin]

Fixes #13499

This PR adds a light-weight quarkus-smallrye-jwt-build extension which will help users create JWT tokens with the smallrye-jwt build API in the native mode.

I've excluded smallrye-jwt-build from the smallrye-jwt dependency as none of the latter's code depends on it - it just has been there before it was moved into its own module - many smallrye-jwt users should benefit; I'll also update the migration notes for 11.0.0.Final that those quarkus-smallrye-jwt users who also require creating JWT tokens will need to add a quarkus-smallrye-jwt-build dependency if this specific change is approved;

Also updated quarkus-smallrye-jwt and quarkus-oidc deployment code and removed smallrye-jwt-build related code and the docs - quickstarts PR to match it will also be opened shortly.

I'll update the soon to be PR-ed quarkus-oidc-client with the quarkus-smallrye-jwt-build dependency asap after the merge as well - as I'll need to support the client credentials JWT authentication there (similarly to how quarkus-oidc does it).

Tests which depend on this API are run in quarkus-smallrye-jwt/deployment, integration-test/oidc-code-flow, integration-test/oidc-tenancy and in the quickstarts/security-jwt-quickstart

I've tested the failing oidc integration tests with mvn clean install -Dnative forgetting it should be mvn clean install -Pdocker-keycloak -Ptest-keycloak -Dnative :-)

Hmm, all of these tests work for me in the native mode...

LGTM

This extension kinda relates to https://github.com/quarkiverse/quarkiverse-jjwt-jackson that @gsmet created?

[sberyozkin]

@gastaldi that extension is indeed related in that it may be able to do some parts of what the smallrye-jwt build extension can. But it is not part of the smallrye-jwt strategy.

I need to tweak the deployment package name a bit

@sberyozkin don't see any note about this in https://github.com/quarkusio/quarkus/wiki/Migration-Guide-1.11

You mentioned in the description: "I'll also update the migration notes for 11.0.0.Final that those quarkus-smallrye-jwt users who also require creating JWT tokens will need to add a quarkus-smallrye-jwt-build dependency"

@rsvoboda sorry, missed it, nothing escapes QE :-).
Have updated it now: https://github.com/quarkusio/quarkus/wiki/Migration-Guide-1.11, please suggest some text modifications if you prefer, thanks

@rsvoboda Just tweaked the guide to remove the requirement for quarkus-smallrye-jwt users to depend on it :-) in view of #14803
