Feature Request: Support Gradle configuration cache

[darxriggs]

Using version 2.0.3 of the plugin, the xjc task fails when using --configuration-cache as follows:

* What went wrong:
Configuration cache state could not be cached: field `outputDirectory` of task `:xjcSome-schema` of type `org.hibernate.build.gradle.xjc.jakarta.XjcTask`: error writing value of type 'org.gradle.api.internal.file.DefaultFilePropertyFactory$DefaultDirectoryVar'
> Extension 'xjc' property 'outputDirectory' is declared as an output property of extension 'xjc' (type XjcExtension) but does not have a task associated with it.
