Add TypeParameters to SqlInvokedFunction

[sviscaino]

The current parser SqlInvokedScalarFromAnnotationsParser.java does not pass along TypeParameter annotations to the function signature.
This PR fixes this gap so we can write SqlInvokedFunctions with type parameters.

Test plan -
mvn test -Dtest=TestAnnotationEngineForSqlInvokedScalars test

@sviscaino The idea is to do the Annotation parser change in a simple PR by itself and then you can do the array functions separately.

Ok, done - I will make a separate PR to generalize the existing SQL functions after this one is merged. I updated the PR title and description.
