Revert add jpa global settings for VFS (true or false) but keep extended persistence context inheritance type (DEEP or SHALLOW)

As per discussion on AS7-dev mailing list, we are not going to convert VFS URLs to FILE URLs. We will still support the extended persistence context inheritance type.

Example of reading JPA subsystem settings from the CLI:

[standalone@localhost:9999 subsystem=jpa] :read-resource(include-runtime=true)
{
"outcome" => "success",
"result" =>

Unknown macro: { "default-datasource" => "", "default-extended-persistence-inheritance" => "DEEP" }

}
