Extend ReflectiveClassBuildItem to support queryOnly option

[zakkak]

queryOnly registrations enable us to register only the metadata without the actual code, essentially reducing the native executable size. For instance, if some code invokes getDeclaredMethods on a class to see if a specific method is available we don't actually need all the methods bundled in the native executable, we just need their metadata. So we could use queryAllMethods instead of methods (which will also pull in the code of all methods).

Note that for the time being we only extend it to support
queryAllDeclaredConstructors and queryAllMethods since we don't have an
option to register only public methods.

Closes #41999

[geoand]

Can you please update the description of the PR and add some Javadoc in the code to describe what exactly GR-21937 brings to the table?
Reading the description of #41999 (and its associated links), I am unfortunately none the wiser about what this does and when I should use it.

Thanks

@geoand done, please have another look and let me know if it's clear now.

Very nice, thanks!
