FormatModelRegistry init fails when iceberg-orc is absent

Please describe the bug 🐞

GenericFormatModels.register() references org.apache.iceberg.orc.OrcRowWriter as a class literal. When iceberg-orc is absent, the JVM throws NoClassDefFoundError (an Error). DynMethods.invoke() rethrows Error directly, bypassing the catch, so <clinit> fails and permanently poisons FormatModelRegistry for the classloader's lifetime.

Stack trace:

Caused by: java.lang.NoClassDefFoundError: org/apache/iceberg/orc/OrcRowWriter
    at org.apache.iceberg.data.GenericFormatModels.register(GenericFormatModels.java:55)
    at org.apache.iceberg.formats.FormatModelRegistry.registerSupportedFormats(FormatModelRegistry.java:207)
    at org.apache.iceberg.formats.FormatModelRegistry.<clinit>(FormatModelRegistry.java:69)
Caused by: java.lang.ClassNotFoundException: org.apache.iceberg.orc.OrcRowWriter

Maybe need to widen the catch in `registerSupportedFormats()`?
