ddb-enhanced: adds EnhancedType parameters to static builder methods of StaticTableSchema and StaticImmutableTableSchema.

[bmaizels]

Adds EnhancedType parameters to static builder methods of StaticTableSchema and StaticImmutableTableSchema.

Motivation and Context

This is a QoL change that allows a static TableSchema to be constructed for a generic class without forcing you to use the raw-type of the class as the type parameter. For use-cases where you may want to dynamically create a static tableschema around a type that is being passed by a caller, this allows you to do so in a type-safe manner.

There are two workarounds I know about this today:

1. You simply use the raw-class and add extra type checking in the methods that get and set the attributes, and any methods that actually use the TableSchema type in its parameters (which is most operations!). This pushes the onus of ensuring type safety on the caller which is not ideal.
2. You create an enclosed dynamic class that implements a generic interface that can be typed with the capture type. It's then safe to use the raw-type of the dynamic class for your TableSchema, but it does not let you export the TableSchema outside that method without losing its type.

Since this change was simple to make and makes good use of the EnhancedType anonymous class pattern that is already supported in the same library, I felt that it was worth making this improvement. We already have prior art in other interfaces in this library that accept EnhancedType<T> in place of Class<T> too.

Testing

Added unit tests.

Looking good in general, but tests can't compile on JDK8:

7825 | [ERROR]     cannot access constructor EntityEnvelope()
7826 | [ERROR]       an enclosing instance of type StaticTableSchemaTest is not in scope
7827 | [ERROR] /codebuild/output/src635456198/src/github.com/aws/aws-sdk-java-v2/services-custom/dynamodb-enhanced/src/test/java/software/amazon/awssdk/enhanced/dynamodb/mapper/StaticTableSchemaTest.java:[1517,57] error: invalid method reference
7828 | [ERROR]   non-static method getEntity() cannot be referenced from a static context
7829 | [ERROR]   where T is a type-variable:
