* Add an InternalSession interface to avoid casting to the implementation in various places
* Upgrade to Guice 6.0.0 and add support for jakarta.inject annotations
* Maven 4 Plugin API
Integrate better and obtain better control over Resolver. These changes did stem from "JPMS module experiment" and are considered improvement but does not implement any functionality related to JPMS module support.
Changes:
* Maven4 should stop "disconnected coexistence" of two type systems (ArtifactHandlers and Resolver ArtifactTypeRegistry), it should unify them.
* Maven4 Core should provide generic and extensible means to introduce new artifact types (fully in extension, and extension should get extended data via "roundtrip" in core/resolver)

* [MNG-7899] Various memory usage improvements
- BatchModeMavenTransferListener removed
- FileSizeFormat moved to top level class
- FileSizeFormat.formatProcess() refactored to accept an StringBuilder as argument
- FileSizeFormat refactored format() methods
- FileSizeFormat refactored, replace DecimalFormat with Math logic to
reduce memory allocation

Upgrade to Resolver 2.0.0.
Changes:
* many UT code used `new DefaultRepositorySystem()` ctor that is gone (was present due SL only), replaced with mocks
* dropped MavenResolverModule Guice module (as AetherGuice module is gone as well)
* updated Resolver version to 2.0.0-alpha-1
* added jdk transport (that prevails apache on Java 11)
* rename of "native" into "apache", deprecate "native" name
* introduce "jdk" transport

Multiple optimizations :
- renderLevel() method use static constants instead of rebuilding the strings on each call
- replace + operator usage with more PrintStream.print() calls to reduce temporary strings creation
- reduce usage of MessageBuilder.a() method usage with more PrintStream.print() calls to reduce temporary strings creation
- replace the builder() method with a static import
- replace String.format with a simple string concat to reduce memory allocation (garbage)
- change static constants to class member in MavenSimpleLogger
- add a setLength(int) method in MessageBuilder to enable reuse
- Use the main StringBuilder to append string instead of using a separate one
- Use the StringBuilder.append() with index to avoid String.substring(), less temporary strings
- Reuse the FileSizeFormat object in the while loop avoiding multiple temporary instances creation
- Non-threadsafe FileSizeFormat instance can be make class instance since its formatProgress() method is only called in a synchronized block.
- add a test in a multi-threaded context
- Non-threadsafe StringBuilder instance 'buffer' can be make class instance since it is always called in synchronized methods
- remove synchronized block in transferProgressed() method, the method is synchronized and the block is not needed
- Remove the Collections.synchronizedMap since all methods that use the transfers map are synchronized
Even though this should not be supported, Maven 3.x is always using the 4.0.0 superpom. So if the version is not a supported model version, simply use 4.0.0. Any invalid value will be later verified by the model validator and eventually throw a meaninful exception.
