fix(java): avoid instantiating abstract meta-share types

[chaokunyang]

Why?

Java compatible meta-share can receive a TypeDef whose root class is an interface or abstract class. Instantiating compatible serializers allocate their root type during read, so those meta roots must not get a serializer that can call Unsafe.allocateInstance on an uninstantiable declared type.

What does this PR do?

• Leaves abstract/interface meta-share roots without an instantiating compatible serializer in TypeResolver#getMetaSharedTypeInfo.
• Keeps concrete values on the existing runtime type metadata or target-class transformation path.
• Adds a resolver-level regression for interface-root meta-share TypeDefs.
• Adds an interface-field compatible meta-share round-trip regression after generated serializers compile.

Benchmark

N/A. This change prevents instantiating serializers for abstract/interface meta-share roots and does not change hot-path serialization for concrete runtime values.
